When banging a girl, alternating between her pussy and ass. The resulting queefs and farts will fill the room with a stanky sea food aroma reminiscent of a clam shack.
Man, last night was great. Me and Jill hooked up. When we were done, her room was like a Cincinnati Clam Shack!

A clam feast eaten whilst rollerblading in tight spandex suits listening to 80s disco primarily hosted in Cincinnati and is often primarily attended by the gays.
I went hard at the Cincinnati clam slam last weekend, I almost spewed twice while hitting a turn!
