When a guy goes down on a girl who is on the rag and when he comes up he has a ring of period blood around his mouth that resembles the effects of drinking red Kool-Aid.
So I went down on her last night, and she was on the rag, when I came up I had the biggest Kool Aid Smile ever.

A long, deep, curving cut across the lower half of the face made by a razor or knife as a calling card by a rival gang or serial killer.
