tonsil painting 

The act of nut busting in someone's mouth. Shooting a load down someone's throat. See protein paint.

I slammed my meat pipe down her throat 'til I was tonsil painting.

Painting tonsils 

To shoot jizz in the back of someone's throat.

"Hey man did you see jess earlier"
"Nah but I was over at her house yesterday painting tonsils"
