Michael Phelpsing

The act of complaining about success.

i.e. Michael Phelps complaining about winning a Silver medal at the 2012 Olympics...even though he has like, 15 Gold metals. Lame.

"Ahhh man, I got a 97 on that test. I should have got a 100. I studied really hard."

"She's totally Michael Phelpsing."
