Bum barfing 

Usually occurs the morning after heavy drinking and can be accompanied with actual barfing. Involves regular trips to the toilet with little or no warning.

Guy 1: Hey dude, awesome night last night but you were wasted!
Guy 2: Yeah, it got pretty crazy!
Guy 1: How you feeling today? Pretty hung, I guess?
Guy 2: Oh yeah, been having a serious bum barfing session all day.

Guy 1: I hate when that happens!

Mantini 

An alcoholic drink that at first glance appears girly but upon further examination is actually quite manly.

Guy 1: Dude, is that a cosmo you're drinking?

Guy 2: Ya right! That's whiskey in there....it's a mantini!
