when a girl thinks she is extremely hot, and puts a bunch of pictures of herself (and sometimes friends) in their bikinis on facebook to show off.
Casey and Marissa changed their facebook profile pictures to the bikini shot they took at the beach. With their cleavage perfectly tanned and their belly's firm, all they could think of was "Dayy-um! We're hot!"
