Pronounced 'batsy.' BATC is short for "bubble ass thigh connection" and describes the 'oh so fine' part of a woman's anatomy which is the curved crease under the butt cheek where the butt meets the back of the thigh. This part of the ass deserves a name and this is it. Don't be shy next time you're making out with a girl... reach down and cup your hands around her ass cheeks and let your fingers lift up from the batc. It feels good!
Bob check that hottie out next to the lifeguard tower, she's got the finest batc (batsy) on the beach!
