brown trombone

This is when you are standing up and a girl is eating your asshole out and jacking you off at the same time.

Me and Suzy skipped band practice and went behind a bush where she gave me a brown trombone.

Suprise Trombone Buttsex

Where trombones yell suprise buttsex and bang their bells together so that the noise echos in the room. Before engaging in trombone buttsex it is encouraged to lube your self up with cream, slide-o-mix, water, or all of the above.
Usually gets strange looks from everyone in the room.

It doesn't have to be with the brass trombones, because trombone is also a code word for boner. It is possible for a man and a women or a man and a man or even a women and women (if parts are there) to engage in suprise buttsex.
just go up to the partner, yell suprise, and pull down your pants and their pants and in engage in angry buttsex without lube.
Lube is optional but if u want to feel anything tmrw use it.

Bass Trombone Family

A group of quasi-retarded geniuses who inherit the younger generation of bass trombonists that have begun to attend the school where the older bass trombone generation currently resides. They are classified in the same way normal families are. I.e. son, father, grandson, grandfather, great grandson, Great Grand Father.

"The bass trombone family here are all retarded geniuses!"
"The best Studio here is the bass trombone families studio!"
"The new kid is coming next semester, son. Your going to be a dadddy and i'll be a grandpappy!"
