Japanese Window-Painting 

The act of spreading plastic wrap over one's mouth and having a person fecalate into the covered mouth.

My girlfriend and I practiced Japanese Window-Painting last night, where she dropped a load within my mouth, covered by protective plastic wrap.

beer window

The sliding rear window of a truck allowing easy access to the beer cooler up against the front of the truck's box and also allowing any passengers in the cab of the truck to dispose of their empty beer cans or bottles into the box of the truck without littering

Dude, will you reach thru the beer window and grab me a cold one from the cooler.

window watching 

When you are really stoned and you get paranoid and peer out the window through your blinds to make sure no cops are sneaking up on you.

"Hey, look at Steve window watching! He is so high!"
