A person usually, female of gender and from New Jersey, who wakes up drunk, drops his or her pants and pees on the floor flexed over a couch (don't confuse with pee-master stretch who pees on the floor while standing). One can use puppy pads to prevent stains to their flooring.
Don't worry her water isn't breaking, she's a pee-master flex.
