The Sack Man (also called the Bag Man or Man with the Bag/Sack) is a figure similar to the bogeyman, portrayed as a man with a sack on his back who carries naughty children away. Variants of this figure appear in many Latin countries, such as Spain, Portugal, Brazil and the countries of Spanish America, where it referred to as el "Hombre del costal", el hombre del saco, or in Portuguese, o homem do saco (all of which mean "the sack/bag man"), and also in Eastern Europe, Haiti and some countries in Asia.
In Spain, el hombre del saco is usually depicted as a mean and impossibly ugly and skinny old man who eats the misbehaving children he collects. In Brazil, o homem do saco is portrayed as an adult male, usually in the form of a vagrant, who carries a sack on his back, and collects mean disobedient children to sell. In Chile, Argentina and particularly in the Southern and Austral Zones, is mostly known as "El Viejo del Saco" ("The old man with the bag") who walks around the neighbourhood every day around supper time. This character is not considered or perceived as a mythical or fantastic creature by children. Instead, he is recognised as an insane psychotic murderer that somehow has been accepted by society which allows him to take a child that has been given to him willingly by disappointed parents or any child that is not home by sundown or supper time. In Honduras and Mexico misbehaving children fear "El Roba Chicos", or child-snatcher, which is very similar to "Hombre del Saco".
In Armenia and Georgia, children are threatened by the "Bag Man" who carries a bag and kidnaps those who don't behave. In Hungary, the local bogeyman, the mumus, is known as zsákos ember, literally "the person with a sack". In Turkey, Öcü (less often called Böcü) is a scary creature carrying a sack to capture and keep children. In Poland children are frightened by the bebok, babok, or bobok or who is also portrayed as a man with a sack. In the Czech Republic and Slovakia, a similar creature is known: bubák. It's a creature without a typical form, connected with darkness or scary places, making children fear but not taking them away usually. The character of čert, the devil, is used for that instead ("Don't be naughty or čert will take you away!"). In Russia, Ukraine and Belarus, buka ("бука"), babay ("бабай") or babayka ("бабайка") is used to keep children in bed or stop them from misbehaving. 'Babay' means "old man" in Tatar. Children are told that "babay" is an old man with a bag or a monster, usually hiding under the bed, and that it will take them away if they misbehave (though he is sometimes depicted as having no set appearance).
Several countries contrast their version of the sack man with the benign sack carrier Father Christmas. In the Netherlands and Flanders, Zwarte Piet (Dutch for "Black Pete") is a servant of Sinterklaas, who delivers bags of presents on December 5 and takes naughty kids back in the now empty bags. In some stories, the Zwarte Piets themselves were kidnapped as kids, and the kidnapped kids make up the next generation of Zwarte Piets. In Switzerland, the corresponding figure is known as Schmutzli (derived from Butzli) in German, or Père Fouettard in French. A similar figure, Krampus, appears in the folklore of Alpine countries, sometimes depicted with a sack or washtub to carry children away. In Bulgaria, children are sometimes told that a dark scary monster-like person called Torbalan (Bulgarian: "Торбалан", which comes from "торба", meaning a sack, so his name means "Man with a sack") will come and kidnap them with his large sack if they misbehave. He can be seen as the antipode of the Christmas figure Dyado Koleda (Bulgarian: Дядо Коледа; corresponding to Father Christmas). In Haiti, the Tonton Macoute (Haitian Creole for "Uncle Gunnysack") is a giant, and a counterpart of Father Christmas, renowned for abducting bad children by putting them in his knapsack. During the dictatorship of Papa Doc Duvalier, certain Haitian secret policemen were given the name Tontons Macoutes ("Uncle-Gunnysacks") because they were said also to make people disappear.
In North India, children are sometimes threatened with the Bori Baba or "Father Sack" who carries a sack in which he places children he captures. A similar being, "Abu Kees" (ابو كيس), literally "The Man with a Bag", appears in Lebanon. In Vietnam, misbehaving children are told that ông ba bị (in the North; literally mister-three-bags) or ông kẹ (in the South) will come in the night and take them away. In Sri Lanka, elders frighten misbehaving children with Goni Billa, a scary man carrying a sack to capture and keep children. In the Western Cape folklore of South Africa, Antjie Somers is a Bogeyman who catches naughty children in a bag slung over his shoulder. Although the name is that of a female, Antjie Somers is traditionally a male figure (often an escaped slave who fled persecution by cross-dressing).
