A Dillon Cap is when the cap to a plastic bottle is placed on top of the drink as opposed to being screwed on. The drink is almost always spilled.
John sees Dillon's Dr. Pepper on the table and slaps it away. It was Dillon Capped and spilled on everybody.
Dillon: DUDE WHAT THE HELL?? MY SODA!!
John: MAYBE YOU SHOULDN'T HAVE PUT ON A DILLON CAP!

Get the Dillon Capmug. To feel a kind of happyness or joy from writing graffiti/street bombing. Can be connected to being a Graffaholic. The word comes from Trigger Happy and was "invented" by HR Crew in Sweden.
