Were a "Bikini" a low-circulation sports equipment brand, theoretically they might make golf clubs, and one could use those clubs, thereby "golfing using a Bikini brand club," or "golfing a Bikini model."

Were there to be a tropical cocktail with a name, in the vein of "Sex on the Beach" or "Hanky-Panky" or "Screaming Orgasm," called a "Bikini Model," one could drink such a thing.

Even without considering the ramfications of bartering of persons (slavery), since a "bikini model" could refer to the brand and style of a bikini itself (rather than the person modelling it), that could easily be gambled as collateral in a strip poker game.

Personally, I think all three of these things are more likely than what TWBA _says_ he is going to be doing, but that's neither here nor there. 

A conservative believes nothing should be done for the first time

Watch out, Twba...I'm not sure she's of age.
