Backstabber

A person who you will think is your friend, only to find out later that this person spreads rumors and lies about you to your other friends.
A roommate who fronts a nice demenor, only because the rent is cheap. All the while attempting to sabbotage your personal relationships for his own gain.

John: Wally, Sarah just told me what you said.
Wally: I don't know what your talking about.
John: Dude you suck, she just told me that you said that I cheated on her and had girls stay at the house.
Wally: I don't want to talk about this right now.
John: Dude you know you have a crush on my girlfriend, and your just trying to sabbotage that because you think she would date your wierd ass.....Fucking backstabber!

backstache

Male back hair which may be manscaped into a decorative form or left au natural. The Fu Manchu backstache is when the tops of the shoulders are hairy, as are the sides of the back (covering part of the shoulderblades), but the center of the back is clean.

So we went to the beach, and Jim took off his shirt to reveal a backstache. It was terrifying in its raw manliness.

Backseat Chess Player

Anyone (or even possibly a group) that stands over your shoulder while playing chess, and the person always claims to see an awesome move for either you or your opponent. This gets so annoying especially when you the moron says, "Oh you didn't see this awesome move!" Then points his fat finger on your board, or touches the pieces. They cause me slight stress due to their annoying hints for the person I am supposed to checkmate...or they keep saying in my ear like a slimy snake, "I see a good move." Sometimes their moves are good, but most of the time they have not a clue what they are talking about and can stick you in a worse situation or cost you a nice piece. Do not take advice from them, and if your opponent is a real chess player they will give them the bird and tell them to shut up or shove off. The best way to repel them is to just ignore them, or flat out tell them you can play better than they can and then prove it in a match.

Stop helping, damn backseat Chess Player.

Backspiration

Backspiration is when someone sweats profusely from his/her back causing a big wet mark. Backspiration is an undesirable occurrence unless actively trying to ward off members of the opposite sex.

Normally I’m super embarrassed by my backspiration, but it sure does help keep Joe, that creep from accounting, at bay.

backchannel

Getting someone's personal contact information so you don't have to communicate with them through a public means.

We were having a conversation on a public web site, but I wanted to backchannel her so we could get more personal.
