Shame Brag 

For when you have done something so shameful but can't stop telling people about it that it almost seems like you're bragging.

"Ok this may be a bit of a shame brag but last night I got so drunk I lost my wallet, phone, ipod, friends, self-respect and woke up in a bin with no shoes on."

OR

"I felt so creepy when I made out with that teenager last night."
"No need to shame brag about that to everyone."

A shamebag occurs when one player dips his testicles in paint and plops his sack on some else's face, leaving a distinctive circular smear. Only croads get shamebagged.

Tony: Hey guys, I think my forehead is bleeding ...

Shawn: No man, you got that red smear when Mickey shamebagged you last night. Face it, you're a fucking croad.
