“Heavy-Fist”
“Slicksters”
“Slobberknockers”
Backdoor Slider.
Bat Boys.
The High Hard One.
The Muffed Punt (lesbian bar)
In Buffalo: Three Dollar Bill’s. (Also the price of drinks.)

Jockey Shorts.
Stud Farm.
Big Red.
Back Stretch.
The Bullring.
Play the Ponies.

The Twelfth Man
“You da Man”
“No, You da Man”

“You da Man”
“No, You da Man”
Don’t worry about pkbites, dear. He’s the one who started this completely ridiculous thread, the tl;dr version of which is he has a tattoo of Yosemite Sam firing guns into the air on his body. And he’s a grown ass man. Also in general he’s kind of… Fox Newsy.
