Biscuity Finger 

The act of placing a finger inside a lady's vagina. Then taking it out and inserting it into a packet of biscuit crumbs. Then placing it in her Vagina once again. Then finally taking it out again and putting the finger into her mouth and make her swallow.

I just gave that chick the Biscuity Finger!
