A Canadian EDM dude named Joel who wears a mouse head all the time. Pronounced dead•mouse but the idiots at my school are always saying dead•mau•5. Don't be like the idiots at my school.
Recommendation: Strobe is a beautiful song.
Me: I wanna go to a deadmau5 (said correctly) concert.
Friend: I think you mean deadmau5 (said incorrectly). Learn how to read.
Me: Why don't you take your own advice.

An extremely popular electronic music producer and performer. He is Canadian born and is currently based out of Toronto. According to various sources deadmau5 (aka Joel Zimmerman) was the 6th most popular "DJ" in 2009.

Technically deadmau5 is not a disk jockey as he performs his tracks semi-live using the program Ableton Live and various gadgets that are not disks, and he does not ride race horses. Therefore neither the words "disk" or "jockey" have anything to do with what he does with music.

Some of deadmau5's more popular songs include "Ghosts n Stuff", "The Reward is Cheese", and "FML"
I can't wait to go to the deadmau5 show!

Deadmau5...is not a mouse as most would believe, but a super hot guy from Canada named Joel.

He wears a mouse mask that covers his entire head, making him look like a dead mouse who plays electronic music, and at times, collapses on stage, causing mass destruction and potential electrocution.
Oh my god! Deadmau5 isn't a mouse?? I never knew that!! I always thought he was a small woodland creature!

Not to be pronounced "dead mau 5". You will be pimpslapped if so. Pronounce "deadmouse".
