Slot-jacked

When you reserved a conference room slot and the person with the time slot before you eats into your time, while looking at you waiting through the window.

Tim slot-jacked the big conference room because he had the president on a conference call and couldn't get him to hang up.

ABBA-jacked

When the party is on fire with nothing but bangers, but out of nowhere some idiot highjacks the aux cord or Bluetooth connection and plays ABBA or something else completely out of the vibe.

Yo, I was playing Ni**as in Paris at this party, and some bitch ABBA-jacked me!
