Wow he ripped ass, he really let out a big ButtMoan.

buttmonkey 

one who, through ineptitude, lack of confidence, lack of superpowers, or sheer ability to kiss ass, is the bitch of everyone around them

If only I could get zapped by a dose of gamma rays; then I wouldn't have to be everybody's buttmonkey!
