"Watch out those turrets!"
An insult word created by a girl named Danielle one day in 8th grade while learning about the real word turret in school (which is a cylinder shaped window which usually protrudes from the side of houses built from the Victorian Era)and she just thought it would sound good as an insult so she told all her friends and changed the definition. It has no particular meaning, just to call people when thay act idiotic or retarded.
"Kelly, YOU TURRET!! Why are you plucking your eyebrows with the back of a CD?!?"
