The act of having either anal sex, or vaginal period sex with a girl and then sliding your horizontal cock up and down her face, making sure to give her a good coat of either blood or feces. This can also be done with semen, however the guy must first ejaculate into a paint tray and then dip his dick in before painting his lover.
Aw dude that girl you went home with last night was so gnarly!

It's all good, I gave her such a thick paint roller, I couldn't tell her from my sister!

Bro, what if it WAS your sister?!

Oh well!
