"______, thy name is ______" is a snowclone used to indicate the completeness with which something or somebody (indicated by the second part) embodies a particular quality (indicated by the first part), usually a negative one.
In most instances, the usage is an allusion to the Shakespearean play Hamlet (I, ii, 146). In this work, the title character is chastised by his uncle (and new stepfather), Claudius, for grieving his father so much, calling it unmanly. In his resultant soliloquy, Hamlet denounces his mother's swift remarriage with the statement, "Frailty, thy name is woman." He thus describes all of womankind as frail and weak in character.
The poet Anne Sexton has a poem called "Divorce, Thy Name Is Woman".
Borrowing directly from Hamlet, in The Count of Monte Cristo, Edmond Dantès (disguised as Abbé Busoni) utters the phrase "Frailty, thy name is woman!" after learning that his fiancee Mercédès has married his rival Fernand.
William Petersen as Gil Grissom on CSI:Crime Scene Investigation says "Vanity, thy name is Hodges", referring to another CSI David Hodges after walking in on him trying to color some of his greying hair with a sharpie while looking intensely at his reflection in a piece of lab equipment.
In the Season 3 episode of Ed, Edd 'n' Eddy entitled When You Wish Upon An Ed, Jimmy says "Victory, thy name is Jimmy" referring to himself as he enters a race with the other Cul-de-sac kids.
