Backstab Murphy

When playing a co-op game, a Backstab Murphy is when one player desperately needs a powerup of some sort (usually health), only to be denied the powerup by his fellow gamer who they happen to be co-oping with.

Player 1: Oh, man. A health pack! Finally!

Player 2: SWIPE!!

Player 1: ... Did you seriously decide to go Backstab Murphy on me?

Backsplash Stain

Spotting and discoloration of a toiletseat's underside resulting from backsplash.

The backsplash stains were almost impossible to remove after yesterday's severe case of diarrhea.

backscatter

When you're fucking some skank from behind, and right before you blow your load, you pull out and scatter it all over her back.

This is where the name for the x-ray machine at airports comes from being that people photographed with these machines appear to have jumped back first on to a cum grenade.

I backscattered your Mom last night. ;)

Ok, Good for you dad?!? :/

Backseat Banter

The obligatory vulgar banter that is initiated by the passengers of a car when one occupant engages in a phone call. Thought to have originated somewhere between late middle school and early high school.

Hey mom, yeah I promise to be home by 8

Oh Tommy, get your cock out of my ear!!! HAHAHA

No mom, I swear it's just Backseat Banter

Cock and Ball Sandwich!!! HAHAHA

I love you mom.

backspite

The action of being spiteful to someone who has originally hurt, annoyed, or offended you.

Cameron used backspite to seek revenge on his enemies, who had mercilessly taunted him.

backseat cleaning

When your parent or parents tell you what to clean as you're cleaning, which is completely unnecessary.

"John, don't forget to dust. Oh, while you're dusting, make sure you're getting the edges of the fan. And vacuum after you're done. And while you're vacuuming, get underneath the couch."
"For fuck's sake, mom, enough with the backseat cleaning!"

Backseat DJ

I'm a DJ at a nightclub in Torquay, England. There's nothing more annoying than a Backseat DJ - the guy that comes up to your DJ Booth and goes "Mate, I don't like what you're playing - if you play insert random genre of music here the dancefloor will fill up!" or "Play something good" - tell you what, here's the decks and mixer, off you go if you think you can do better! ;)

Some backseat DJ was trying to tell me what to play all night - played what he asked for and the floor emptied!
