One who practices butthole surfing - the act of intravenously injecting an aqueous solution of both LSD and heroin (or another interchangably potent opioid analgesic). The author strongly discourages this kind of behavior, being considerably more risky than IV self-administration of either compound independently, which is saying alot.

The name was of course also adopted by the well known Texan acid-punk band the Butthole Surfers.
An example of this kind of a butthole surfer is totally superfluous by virtue of the self-explanatory nature of the above definition

A Butthole Surfer is that one guy at the beach who always exaggerates about how big the swells were last weekend, even though they were only 4 feet and still proved a challenge for him.
Dude, Dave was being such a Butthole Surfer. He was bluffing about how there were 25 foot swells, but they were only like, 6 feet man.
