A Butthole Surfer is that one guyat 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 ButtholeSurfer. He was bluffing about how there were 25 foot swells, but they were only like, 6 feet man.
Free Surfer is a self-chosen descritption for lifestyle victims in the realm of hipsters practising the sport of surfing. Free Surfers are most likely to be identified by attention seekingsocial media behaviour, blabbering out information about surf spots, resulting genuine hatred by pissed-off locals.
1. A dude who "surfs" (either on the 'Net or at the beach) for cute chicks with great bodies.
2. A chick who offers her body to horny studs in exchange for their financial indulgences; she "rides the tide" (i.e., gleefully "glides on the crest" of her present lover's surplus savings) all the way into shore (i.e., to the point when the soft-skin-'n'-firm-flesh-craving dude's excess saving are eventually depleted by her wanton spending), then casually picks up her surfboard without even so much as a single backwards glance at her fiscally-attenuated ex-benefactor, and gracefully pirouettes off along the seashore of life in search of the next lonesome sucker sitting all by his lonesome on da beach of bachelorhood.
Financially-solvent hunks of any age should be wary of any hot chick who suddenly/unexpectedly comes onto him "with both barrels" and offers him a no-holds-barred good time, especially if he's not all that young or good-looking --- she may very likely just be a body-surfer.
