A mix of wet paint and paint that is starting to dry.

Where you see it.

1) when stirring the little bit of paint at the bottom of a 5 galllon bucket of paint.

2) when it’s left in the pan and you dry to mix new paint with stuff that’s starting to dry. You roll it on a wall and you get those little slimy particles on the wall.
1) “I’ve been stirring this bucket and there’s a lot of paint fat mixing in.”
2) Her: “Ahh, that’s rolling terribly on the wall!”
Him: “Well, we left the pan out and I mixed new paint, and you get paint fat.”
Her: “Paint fat?”
Him: “Yeah, paint fat. It’s the excess paint, like fat.”
Her: “Well, fix it!”

Get the Paint Fat mug.
Saying this phrase will get you sent to Facebook jail. Source: Personal experience. Refers to: the game Elder Scrolls IV: Oblivion and the quest “A Brush With Death” where you enter a painting and fight painted trolls which will drop painted troll fat when killed.
I follow a gibberish page on Facebook and decided to randomly comment “painted troll fat” which got me sent to Facebook jail. I got 3 days for my 3rd offense for equally stupid reasons. Thanks mods!
