The act of gaining an upskirt view of a female through covert action for the purpose of discerning whether the target is wearing undergarments. (If the answer is no, you done shot yourself a beaver skippy).
"Dude, I was at the mall today. I rode up the escalator for an hour and shot like 3 beavers."

The act of a woman spreading her legs while wearing a short skirt and no panties so you can see her vagina.
I was sitting in class and Amy was shooting beaver at me from across the room.
