What is Yer Mom?
1.
A great insult to fling at people. Or just something to say when there is nothing else to fill the void. Also, the source of many dirty jokes.
A) "Yer mom is so -insert insult here-
B) Person 1: "Hi, how are you?"
Person 2: "Yer mom!"
C) Person 1: "Hey, you poked a hole in my balloon! I hate you!"
Person 2: "I poked a hole in your mom last night."
2.
Widespread use of this phrase was brought back to life after the movie Napolean Dynamite hit theatres. This is generally used as an insult, though it can be thrown into a conversation at any point in time.
Andrews - "Yer mom's so fat... that when we tried to graph her on our calculator... there was a stack overflow error."

the best insult in my mind. it also works if you get asked a question and dont want to answer it or just feel like wierding someone out. it also works if you get insulted. also one of the best starts to jokes. (a.k.a. yer mom jokes)
