Infant Sorrow is a fictional band created by Russel Brand, or Aldous Snow in the band, for the Movie "Forgetting Sarah Marshal." Also used in "Get Him to the Greek." It uses funny lyrics like "When life slips you a Jeffery, Stroke furry wall" referring to Get Him to the Greek when the main character has smoked a Jeffery and is think he has a heart attack and is told to stroke a furry wall to calm him down, which does not help.

An exclamation made when your friends or family are teasing you to a point where you can't handle it anymore and a hissy fit is in order.

Derived from a YouTube user's famed outburst following Britney's lackluster performance at the 2007 VMA's.
