To get hit in the mouth with the butt of a rifle.
"He better be quiet or someone will pistol-whip him or worse. Like getting butt-stroked."

Get the butt-stroked mug.
The act of using the butt end, or stock of a rifle to strike an enemy across the face, chest, neck, or other body parts. Taught to members of the military as means of defending yourself in a hand-to-hand combat situation when all else fails, or just for the fun of it. The butt stroke is highly effective and extremely painful for the unfortunate fuck on the receiving end. The butt stroke is with a rifle what a "pistol whip" is with a handgun. The butt stroke can be properly executed with any type of firearm fitted with a shoulder stock, however, it is most effective with heavier weapons, such as an M240B of the M249 SAW. If you are properly equipped with enough muscle, a .50 Cal M2 HMG is quite the preferred tool of choice, however, due to it's weight, size, and the fact that it's normally mounted can be a challenging obstacle.
"If you don't back the fuck up I'm gonna butt stroke you into next fuckin' year!"

"John got drunk and butt stroked Amy right in the face! Oh, I hope she has medical insurance!"

"We were down to our last mag and then we got overrun, so we jumped up and butt stroked haji long and hard!"

"Welcome to Wal-Mart, how may I help you?"
"Yes sir, I'm looking for a rifle."
"Are you looking for a hunting rifle or something less powerful, for say, target shooting?"
"Oh, no sir. I need good butt-strokin' rifle."
