well...this is going to sound kind of strange....ok so yes it does mean to have sex but the REAL definition is: the last stroke when you are about to go off a waterfall in a kayak. when done correctly it propels you past the recirculation at the bottom, but there is a risk of back-breakage

The act of lifting the bow of a whitewater kayak while going over rocks, waves, or waterfalls, in order to launch over hydraulics ("holes") or rocks. The name is derived from the sensation that it gives the kayaker, which is similar to rectal administration of drugs.
Charlie had such a sweet boof off of Little River Falls! All the cool kayakers are doing it - why plug the hole when you can boof it.

Slang for meth. Used to describe crystal meth in the 785 area code. Originated from the descriptive feeling one got when smoking or shooting meth during the 2000's. When users repeated blurted out "boof" after large hits and where asked why , they answered "everytime i hit your shit my head goes boof" and slowly dealers throughout the 785 coined "boof" slang for its crystal meth, ice, tina, twack, etc.
