The act of fingering a woman's ass hole and keeping it in a bottle of milk for 15 minutes and dunking it in the sugar of sour patch kids.
My wife wanted to spice things up a tad and she asked for a Sour Finger... it still smells after 7 months.

Instead of putting someones hand in water to make them pee you just stick their hand in your pee.
PS: Great for sleepovers.
I put his hand in water while he is sleeping but he insn't peeing. Screw it he's going to get some sour fingers.
