a sexy dress, that every woman has, which shows off her goodies; it's worn to attrach guys (while making her own guy jealous). Also known as a Fuckum dress. This was thought of by Martin Lawrence, not Beyonce.
"...you go in the room and put on your fuckum dress (freakum dress). You be like fuckum girl, fuckum. Fuckum girl, fuckum. Fuckum girl, fuckum." -Martin Lawrence(You So Crazy)
