Combat Onesie

The act of someone in the military taking a piss. In the Military they tend to add the word combat in front of everything.

Onside gift

A gift purchased for a Yankee Swap or similar random gift exchange program which the owner attempts to end up with him/herself.

As the only one who likes coffee, Joe bringing that espresso for the Yankee Swap was a total onside gift.
