When a random person (usually a hobo or homeless person) goes up to any male walking down the street at random, and out of nowhere, quickly pulls down their pants and jacks them off at the speed of a jackhammer as they immediately ejaculate with no warning. The person doing the act then sprints off. The entire process is completed within a matter of seconds. This often occurs in Casper Wyoming which is in Natrona County.
Jake received the Natrona Jackhammer and didn’t catch a glimpse of the culprit!
Woah! I just got Natrona Jackhammered!
My friends and I are going to Natrona Jackhammer some people.

When a man spreads the woman's vagina flaps and attempts to stick his head into it. This normally ends up with a trip to the ER as it is not safe for both genders. This can be done with the same sex (see Finnish jackhammer).
