dejafuk

When someone randomly remembers to tell you something that immediatly causes you anger or dissapointment.

"Dejafuk! How the hell could he just remember to give us homework on friday?"

"Oh dude, sorry to dejauk you but yesterday...I gave your dog some beer and he ran into a wall and didn't get up"

"I dejafuked my girlfriend today by putting laxatives in her oatmeal when I left the house this morning haha."
