When a person's index and middle fingers are pointed outward, the thumb raised and the rest of the hand is balled into a fist, and the index and middle fingers are inserted into a vagina, it is known as a Twat Gun.

What would normally be described as a "tampon applicator". It's that plastic thing you find in the bathroom garbage can.
I was takin' a piss and I looked down at the garbage and I saw one of them "twat gun shells" in there. Grossed me the fuck out!
