mack wake up 

To repeatedly fire a .50 caliber weapon (such as the .500s&w, .50BMG, 50-70, .50AE etc) in the air several times to wake somebody up or get their attention much like Richard Machowicz when he fires his .50 caliber weapons on the badass tv show "Future Weapons".

*Kyle and Joe at the shooting range*
Joe: kyle!
kyle: ...........
Joe: KYLE!!!
kyle:........
Joe: *fires desert eagle 4 times*

jimmy-up the mack 

A Vandergrift Casino Theatre prank used to make freshman stage crew people go insane trying to find out how to "jimmy-up the mack". Bottom line: the "mack" that needs to be "jimmied-up" does not exist!

Cast member: "Go jimmy-up the mack, Bob"
Bob (first year stage crew): What the heck is a jimmy-up the mack!

Cast member: Just go do it!

Bob: What is it!

Cast member: The show will be ruined if you don't jimmy-up that mack! Now go!

Bob: but!....but!

Cast member: GO!
