Jacks

Another way of claiming your rightful ownership to a seat. Similar to Quack Quack or Dibs. The art of stating Jacks is to make sure that a 3rd party hears you.

John walks back downstairs after getting some pizza, sees his spot is taken.

John:"Yo, Freddy I got Jacks"

Freddy:"He got Jacks?"

3rd party:"Yeah man move your ass"
