When you go into a restaurant, eat a fine meal, and then go into the restroom, where you proceed to shit on the ground, obtain the plunger, stick it into the crap, and plunge it against all the walls and mirrors, creating a horrifying scene for someone to clean up. Recommended to Dine & Dump at the same place as many times as possible.
Dude, me and Tyler went to Calabash seafood and did a Dine & Dump. It was disgusting. I wish I could have seen the employees face who had to clean it up.
