Oat Bag 

A sex act. While having sex doggy style a dude jizzes in his hand and hops on the girls back like he is riding a horse. He then reaches around and puts the hand he just jizzed on over her mouth and yells OAT BAG! The other hand can slap the ass, or remain idle.

Stephanie is super pissed at me for giving her an oat bag and slapping her ass last night.

Nothing is better after hot sex like a nice oat bag to hold me over until next time.

Reverse Oatbag 

The act of throwing up into a vagina.

I made the mistake of eating 25 buffalo wings and 2 shots of Jager and ended up giving my girlfriend a Reverse Oatbag while third basing her.

What you get after working all the time and getting paid just enough to survive.

What the farmer gives to his plow horse after working all day. Just enough to survive so he can plow again tomorrow for another oat bag.

"Oat bag! Ive got my Oat bag! Oat bag just for me!"

Compensation for a menial job where you receive just enough to make it to the next pay day.

What a farmer gives his plow horse so he will have just enough energy to work until his next feeding.

Jeff took pride in his job at wendy's until he realized that no matter how hard he worked it was all the same oat bag at the end of the day.
