a name for an extremely fucked up motherfucking bitch who has a chod and yells at people for pointless reasons that no one not even God knows. Also hates the word quack and anyone who pronounces the last name rosicky Raw-sick-ee. If you know some who is a uecker chances are they are the Antichrist and have dyke orgies at the nearest gay bar. Approach with caution. If you see one alert authorities before it is too late.
"hey, that teacher is definitely a big uecker, plus it looks she has been worshipping the devil.
