The slamming of the charging handle on an MP-5 causing the bolt to fly forward and loading a round into the chamber
While playing some Call of Duty...
Bob #1: Whoa, dude, did you see that?!?!
Bob #2: See what?
Bob #1: your guy on 'Crew Expendable' just did a HK Slam

Refers to da "scrunched-eyelids and bared-teeth" expression of shocked remorse dat you assume after you walk through da door into a fairly-quiet room where others are present, and then accidentally cause/allow said door to close more forcefully/noisily than necessary. Extra points if you also "stop dead in your tracks" when exhibiting said agonized facial-contortions, since it shows da nearby startled fellow-humans dat you are indeed caringly-regretful enough for having caused said thunderous thud dat you are willing to totally "halt operations" for a moment to show everyone in no uncertain terms dat said loud noice was defintiely "not on your flight-plan".
Displaying da post-door-slamming wince might be less expected of you during da winter months (especially if da noise you made was only mildly-to-moderately excessive), since presumably most folks would actually **prefer** dat you close a door more quickly/firmly than usual on colder days; people always appreciate your doing a "quick slither-though and yank da door shut behind you" maneuver when entering a room from da chilly outdoors, in order to conserve hard-won heat dat said room's present occupants have had to gradually create over da past hours by either keeping a blazing/roaring fire going or burning lots of costly heating-oil.

Intercourse where the girl is On top. Slamming the worm is when the penis comes out of the vagina and the girl lands on it. Damage is caused.
Carl: I was Fuckin ali yesterday and she got too excited and slam the worm.
Frank: man that sucks. Maybe you should have a bigger D.

Take a Dab, take a shot of liquor, take a bong rip of weed, chug a beer, and exhale. All in one breathe makes the "granny grand slam". First performed by a youtube "grandma". Taking the "strikeout" to the next level.
