The art of speaking each word backwards while keeping the standard continuity of a sentence. Variations range from changing the sound of the letters or keeping their original sound.

Boy: I Evol Uoy. (Eye eevol ooh-oy)
Girl: What?
Boy: I love you! I said it backwards; it's called 'Backspeak'.

Backspeak 

Making fun of a person indirectly for an insecurity directly to their face with literary skills and generally going over thier head with a story about some random comically named person. The story usually parallels the person being made fun of, the more people being in on it the better, or worse if you are said victim. Generally works on the uneducated, potheads, or any mind susceptible to gullibility.

"So what do you do for a living?"
*backspeak*"I care for autistic orphans"
"Really?"
*backspeak* "Yeah, they don't know how to take a hint, it's as if my efforts to get them to stop talking to me are received by autistic ears."
"They're autistic?!"

Backseat Gamer 

Like a backseat driver, a backseat gamer is a person who tells you what to do in a game that you're playing while you're playing it.

"No, shoot that guy! Not that one, that one! The other guy!"
"WILL YOU STOP BEING A BACKSEAT GAMER PLEASE?"

Backseat DUI 

A backseat DUI occurres when a sober person is driving an intoxicated person home, and the intoxicated individual is giving the driver shitty directions, and false instructions to turn, and then saying "No, No, not this street..."
This causes the driver to speed up, slow down, and begin to turn, then swerve back into the driving lane, leading others observing the vehicle from the outside to believe that the driver is DUI.

"I was driving Marcus home the other night from the local water hole and he kept telling me to turn and shit and I was all over the place and then I got pulled over, but it was cool, the cop realized Marcus was just backseat DUI."
