Backhead 

Performing a ridiculously stupid act whilst playing video games or in real life. This word can also be used as a name for someone who is ordinarily performing stupid and/or asshole-ish acts.

Game Example (GTA V)

Raul: *Picks up friend in Elegy* Where do you wanna go?

Matt: Take me to the clothes store!

Raul: Okay! *crashes into every goddamn pole in GTA then proceeds to crash into a bush and then finally proceeds to drive into the clothes store*

Matt: Bruh wtf! You drive like a fuckin Backhead!

Alternative Game Example

Anthony: *Switches off inverted setting on game and tries playing* Ahh hell nah what kind of backhead logic is this

3rd example

Raul: *blows up random cars and accidentally kills a friend passing by*

Tray: Yo wtf is wrong with you, you fucking backhead!

Arch-Angel-Buttcheek-Backspread 

A term coined by YouTuber Ian Carter, A.K.A. Idubbbz, meaning to lean over in the shower as to let the water go in your butt crack.

I kept on getting hair stuck in my asshole, so I used the Arch-Angel-Buttcheek-Backspread and it cleared right up.

backhead 

Backhead is quite literally the back of the head. It is the part of the human skull that protrudes away from the face. When viewed from the side, backhead is the portion of the head that hangs out over the back of the neck.

Bruce Bowen has ridiculously large backhead.
