Something you say when your friends or people around you say something so stupid that it's hard to think of why they said that
Person 1: Dude did you know that ice cream has to stay cold.
Person 2: (sighs) Derp
Person 1 - "dood u sucha derp"
Person 2 - "ya me kno dood"
Persons 1 & 2 - " hahahaha"
The word derp is a word for everything and anything. It can be whatever word you want it to be. People may think your stupid but your just smart.
