Ohh, a couple.
"Hoss" was a humorous one that I had in high school. I sucked at football (in my opinion), but I've always been a phenomenal weight-lifter. Much like Deni, this is also due to my build and overall size. It didn't stick, but a circle of buddies referred to me as that quite often. I broke some dude's knee-cap using my helmet senior year in football. "Hoss" became "Killer"

He shouldn't have cheap-shotted meeeee~
"Gimp" is one my old college buddies and Brother still make use of. I have a knack for suffering pretty bad injuries. It's very evident that I've been banged up given how I walk, my gait, and my shoulders. I have a confident swagger of sorts, but the right leg makes it look weird. Someone once came up to me and asked if I lost my leg in Iraq. I just kinda went "NO I LOST IT IN YOUR MOM LOLOL GET IT."
"Faggot with a lame taste in video games & animu. PLAY CAVE STORY." This one is self-explanatory. You haters
Jam it back in, in the dark.
