Tribbing

Sex acts that involve fecal matter in any shape or form.

We went to a nice party, we started tribbing hardcore when we got home.

Trib Joint

A Trib Joint is when 2 pieces of wood are notched so they locate within one another, mimicking a sexual act usually performed by lesbians.

Dave, we need to make a shelving unit for the bookstore, I was thinking of using the Trib Joint construction method.
