look up any word, like blumpkin:
 
1.
A way for creepy people with porn mustaches to say hello or "I understand". Hold your fingers in the shape of guns (use both hands for maximum effect) and point at someone who just arrived. Bend thumbs to simulate shooting your finger guns and make a clicking sound with your mouth. May be accompanied with a wink in extreme cases.
That dude that looks like he just fell out of the 70's just offered me a piece of candy and then winked and gave me finger guns. I said no.

2.
Used by placing the "gun" to the side of one's own head or under the chin, as if committing suicide, to indicate a strong desire to be put out of one's misery, either from boredom or exasperation.
-Hey, have you seen jose's picture?
No, why?
-He has a finger gun to his head!
Oh, I think he wants to take away his life:\

What douches do in two-person photos. The d-bag will put one hand on the back of his companion to relax and distract the person. With the other hand he will make a gun shape and point at the person's upper body. The other person is now a douche too, but isn't aware of it because they're looking at the camera.
Goddamnit Bob, why do you always douche it up with the finger gun!

4.
the act in which one person provides sexual stimulation for another person by making a gun with their fingers, before thrusting the 'gun' in and out of another persons holes while making a shooting noise with their mouth.
Situation 1:

John: "I was out last night, and this dirty hoe asked if i would finger gun her, what the fuck!?"

Situation 2:

Person 1: "I was finger gunning your mum the other day and.."

Person 2: "Wait, what!?" *Beats the shit out of him*
