butt marks 

The identation of a person's ass. Most common in chairs and sofas, when a person has been sitting in the same spot for a long period of time.

See ass groove

Charles sat around and watched college football on a lazy Saturday afternoon. When got up to used the bathroom, he left a large butt mark where he was sitting.

Buttmark

The soft folds of toilet paper that you place in between your buttcheeks as you stand up to give a courtesy flush so the cold water doesn't splash your sensitive baby soft skin.

After AV was done blowing the smelly pootinkies out of his garehole, he needed to give a courtesy flush so he placed a buttmark between his cheeks and flushed. His butt didn't get wet or dirty and the bathroom was no longer smelly, everybody wins, except your mom!!

When a faggot marks your ass for the taking.

Your in the pub and a queer laces your drink with rohypnol - you've been 'buttmarked'
