It means to place an object in your ass. A word commonly used in prison when sneaking drugs inside. Often confused with "cheek" which means to just place the object inbetween the butt cheeks but not actually in the asshole.
That hardcore gangsta had to boof a bag of weed to sneak it past the guard.

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.
