When a girl bleeds from her vagina and a guy gives her a creampie(ejaculates in a girls vagina)and keeps going till the blood mixes with the cum.
Joe:man I got it on so hard with my girl-friend that she was just covered in purple yogart.
Ted:Man Joe it must have been beast mode last night for you.

It's another absurd way of saying a dick which spurts out cum or sperm whichever. It's not actually purple but you get the jest.
