Backseat Best Friend

When your some ones best friend for a large amount of time, then after they lose all their good/best friends they cling to you. Then around 6+ months later when he/she gets their friends back, they start pushing you away slowly and moving towards their old friends again, but still call you their best friend.

Situation is made worse when said person is your Ex and you have feelings for them.

MAKING THE BEAST WITH 2 BACKS

to copulate or partake in coital activity; to do the bone dance; have sex.

The saloon keeper and the town trollop were 'making the beast with 2 backs'like 2 jackrabbits on steroids atop the pool table, after he locked the saloon doors, as the last sot vacated the premises at 3 a.m.

backslider

A backslider is someone who has no honor, someone who is full of deception. A liar and thief who always taketh and never giveth.

Bare your windows and lock your doors, beware the backslider roams the moors.
