ownerous

A task so challenging it owns the crap out of you. Pun on "onerous", which has a slightly, but detectable, different pronunciation.

Man, I am wiped out trying to get that code finished by the end of the week, it's really ownerous.

piece offering

Another term for makeup sex, where "piece" is for "piece of ass".

You still fighting with your girlfriend?

Nah, she dressed up sexy and made a piece offering last night.

Nice!
