Screwball (ice cream)
A screwball is a type of frozen confection that first appeared in the 1970s. It consists of a flavored sorbet like frozen dessert inside a conical, plastic cup with a gumball at the bottom; the flavor of the ice is usually raspberry ripple. Several prominent brands produce screwballs, for example Asda, Popsicle, and Eskimo Pie. The name was originally a commercial product name but is now used to describe all such ice cream treats, whoever makes them. The product does not qualify as ice cream under USDA guidelines. 
'Two Ball Screwball' is a brand name (in the United States, a registered trademark) for a screwball containing two gumballs. The original flavor was cherry but it has also been introduced a multiple flavored twist of lemon and blue raspberry. As with all screwballs, the shape is that of an upside down cone with the gumballs at the bottom.
