its what all the quirky teens say to look quirky when they have nothing to say or just for fun
person #1: hey whats your favourite color?
person #2: your mom
Your mom was an old school classic of a come back and might me still ro this day. But do NOT use if there mom is dead or if they want to forget there mom. But it is still a joke so don't tack so seriously.
gad damnnnnnnnn he almost as fat as your mom
calling some one an idiot and saying that your mom does "bad things"
I bet that is not what your MOM said last night
A comeback
Jane: "You know who else suffers from dementia?"
Bob: "your mom XD"
Jane: "kys"

Friend:"Your gay"
Yoy:"That's not what your mom said last night"
