A valid response to any insult and/or challenge. Even if you are unable to back up the line, saying it is enough to make anyone else's argument invalid.

Stemming from the show Gurren Lagann as a popular catchphrase.
1: You are so stupid.
2: Who the hell do you think I am?!

1: You couldn't win if you tried.
2: Just who the hell do you think I am?

One of the most popular lines from the anime Gurren Lagann. When using this line, you put on those W that go like this: \/\/, only longer. This is because the most popular character, Kamina, wore them every time he said it.
Guy 1: Do you want a sandwhich?
Guy2: Just who the Hell do you think I am!?
Guy 1:...I'm gonna take that as a no.

the song from dead island that goes like

"Ha ha ha, you ain't scared. Yet. Things that go bump in the night. Me, Sam B. Heh.

Shrunken heads, broken legs, body parts on the concrete
Cut 'em up butcher style, gators in the swamp
Red light, leave 'em dead, runnin' like a track meet
Scared of nobody, what you motherfuckers want?
Believe me when I tell 'em I'm a boogeyman beast
Leave 'em slashed from they head to they feet
Pin pricks to the chest of a bitch well earned
Cookin' meat, cannibal tryna eat

I got a zombie army and you can't harm me
Who do you voodoo, bitch?
Drink blood like a vampire without warnin'
Who do you voodoo, bitch? Stand up!
Sam B got the thing that go bump in the night

I can say the rest but its too long
Guy: Heard of Who Do You Voodoo, Bitch?

Dead island hater: Is it from the shitty zombie game with a trailer with no gameplay?

Guy:*Laughs in rage mode*

BREAKING NEWS! DEAD ISLAND FANATIC FOUND DEAD! IF YOU HAVE ANY INFORMATION ON THE KILLER, REPORT IT NOW!

It's a rhetorical question you say when somebody is on some other shit and/or acting all cocky
"What you just did is morally unacceptable, I'm going to expose you and hope you learn your lesson."
"Who do you think you are, Judge Judy?? LOL."
