"What? You sick?"
(*running and groaning*)

Butt Hummer 

Sexual act; during anal sex (typically best between men) at the point of climax, the recipient of the load blasts a forceful, monstrous anal queef vibrating the schlong as it makes the deposit.

I was slamming this dude's ass last night and he gave me a crazy dope butt hummer. I was in heaven until I realized he back blasted me with shit streaked sperm.

butt surfing 

Sliding your hard-on up and down inside your (male or female) partner's butt crack, usually gently slapping your lower abdomin and hips against the butt cheeks as you 'surf'.

May involve slipping the tip of the cock into the anus you pass by it on each 'ride'. Butt surfing may, but not necessarily, cumulate in giving your partner a full on ass fucking. Use a condom if you do this.

Works best on a tight, rounded ass.

After a good day at a beach, Brad and I took a shower together. I whipped off his red speedos, lent him against the tiled wall and gave him a good butt surfing.

butt stroke 

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."
