the best comeback ever in existince
by CoolxZx1155 May 31, 2018

The only perfect comeback that is uncommonly used against the devastating phenomenon called Ur Mom Gay. Can only be used for 2 times in a row or else it will no longer make sense and make you look like fucking retard.
One: Ur Mom Gay.
Two: No U
One: *Breaks all of his fuckin' bones and disintegrated away like Spiderman*
Two: No U
One: *Breaks all of his fuckin' bones and disintegrated away like Spiderman*
