That sounds a lot like me in college except I wasn't a funny guy, I was a badass.
Sometimes, when someone would make mad, I would say something like, "Shut up, stupid-face!" or "You're a big dummie, ya dork!"
Sometimes, if someone was talking to me and I didn't like them, I wouldn't even listen to what they had to say.
One time I left history class early cuz I was BORED!
This other time, instead of walking on the sidewalk, I walked through the library lawn in clear defiance of the sign that emphatically posted "KEEP OFF GRASS" Damn right.
Yeah.
Badass.
