Obama Sack

A clear plastic bag, full on coins.
Named after Obama, because they are both full of change.

Zack - I'll throw it with the rest of my change into my obama sack.

Condom sack

Used as an insult for when someone is being more then a douche. Condoms have cum inside them after being used, thus making it more disgusting and just gross. A large sack of them is a lot worse then a douche.
You're such a condom sack man! Just go and punch him in the face!
