A "comeback" you use when you're too trash and uncreative to make a roast.
But wait! There's more. The autistic version of this saying would be "no u".
There are quite a few variants of this
fucking retarded saying:
"
I know you are but what am I"
"You are too"
"So are you"
"You are what you called me"
"That's
what you are too"
"*literally copy what they said*"
"You are *insert what they said* too"
And for a bonus, show off how angry you really are by putting a smiley. Show you are also angry (but not as angry lmao) by putting an angry face. Don't put emojis, fuckface.
See? I came up with those easily. Next time you get in a fight, don't say shit like this. It only makes you closer to defeat.
