look up any word, like dog in the bathtub:
When you cut along someones ass hole across their taint and along to their genatalia. This will create a great hole that must be dug out and cleaned. Although it is no longer a taint, it is called an Alpha Taint because of where the incisions are.
Nolan: Wow Clara, thats a nice Alpha Taint you have there.

Clara: Yea I know, you can stick your whole head up my Alpha Taint
