…you fight like a cow!
I had a buddy who teed himself up for your mom jokes constantly. I swung and hit pretty much every time.
One evening he had enough and blew up. “God, you’re such a dick! You must be the biggest dick in the fucking world!”
“Well, I fit in your mom just fine, so I don’t see what the problem is.”
I just don’t think a pre-packaged comeback (hilarious as many of these are!) can truly ‘destroy’ someone. It needs to be personal to the situation to really hit them deep. Unfortunately I can’t think of an example.
There are people who did not stand at the front of the line when intelligence was gifted . But that guy wasn’t even invited at all…
“The best part of you ran down your mother’s leg.”
The best part? My friend’s dad said that to him when we were kids. Yeah, he was a major asshole. Also, not scientifically accurate. He was pretty stupid.
