Your sister

Its a more recent variation of 'your mom'. is often used to insult somebody with or without a sister. used more often now as your mom is becoming out dated. (still only used by douche bags)

first guy: i heard a noise last night what were you doing?
Douche bag: your sister
surrounding audience: OOOOOOOHHHHHHH!
random guy: i like turtles
2nd douche bag: i like your sister
