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 #2: See what?
Bob #1: your guy on 'Crew Expendable' just did a HK Slam

Get the HK Slammug. 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.

Get the slammed ass whoremug. When four or more of your friends hook up with the same girl at different times. Can only be completed if each person goes all the way (i.e. hitting a home run).
