Song of the Day: Party Boyz "Flex"

I have no idea who the The Party Boyz are. They may as well be a reincarnated form of the Shop Boyz (remember them?) who have finally given up on that whole rap rockstar thing and tried something new for all I know. But apparently "Flex" is a popular song and dance from Texas...and it's pretty catchy!
