bumping clams

the act of rubbing the female clitoris together with another female clitoris

bumping clams refer to the opening of a clam shell, revieling the clam and bumping and grinding with another "clam" or clitoris until the friction generates a pearl....or an orgasm.....depends on whether we are talking clams or clitorises....
