Tall One

A tall one is when you jerk off while lying down and your cum comes out in a tall stream usually landing on your forehead, shoulder or if your lucky, in your mouth.

Man I was jerking last night and busted a tall one, it landed on the fucking ceiling!

The funny one.
The smart one.
The one that could always cheer you up.
