I dumped on Block Island on a little 3 footer back in the fall. I actually timed it to catch the wave and have a little fun, but blew it by not leaning on my paddle on the inside (Low Brace).
I am finding a few articles on "butt surfing"

and found one site I liked on this subject.

excerpt:
When everything goes horribly wrong and you lose control of your craft you will wipe out. Depending on the size and nature of the wave this can be very spectacular, even painful, and may well involve lots of unintentional capsizes and cartwheels. If you don't bail out of your boat, you'll find your self being pushed sideways and bounced in towards the beach. This motion is known as the bongo slide, and mastering this skill is the first step towards feeling truly comfortable in the surf.
I realize that practice is what it is going to take. Just at the beginning of the Nahant Causeway I have seen the surf yakkers having a blast. In the spring I will join them with a bicycling helmet,PDF and a wet suit. I will make sure to bring some food \\ drink \\ smoke to induce them to teach me. The Bongo Slide
