ur mom

a default comeback to almost any insult someone throws at you.

can also be used when you really dont have a reply to the question given to you.

also a comeback that idiots at your school may use.

person 1: hey what's ur dumbass doing tonight?
you: your mom

person 2: what did you get for number 3?
you: your mom
