Mega douche is someone who has exceeded all expectations of the common douche. One who has reached such a level of douchiness that people would rather play in traffic than deal with that person.
Man, look at that crane operator he's such a mega douche why did they send him out here, he should go under a rock and die!

It takes 5 douches to make a douche nozzel and at least 5 douche nozzels to make a meeega douche! which has more douchiness than aleast 15 annoying people.

Sac: Oh yeah which one?
Mac: MEGA DOUCHE
