Goofadelic is used to describe a goofy action. Particularly actions that are spazy and uncalled for yet still slightly funny.
Person one: Dude, quit doing that dance, it's so goofadelic.

Person two: I don't care it's funny!

Person one: It was funny five hours ago, just stop.

Person two: *continues doing the dance*
