Back Up The Train

used to say, "hold up" or "wait a minute" or "thats not true" or to express disbelief.

1. A loud girl, Joanna is talking to a boy, Liam for the first time:
Liam: you seem really quiet Joanna
Joanna: Back up the Train! I never shut up!

2. Joanna is talking to her friend Lisa later that day:
Joanna: so I talked to Liam today!
Lisa: BACK UP THE TRAIN YOU LUCKY DUCK!

3. Lisa is talking to Rebecca later
Lisa: Rebecca you're kinda annoy-
Rebecca: Backup the train & don't let that thought out of the station!

Back door bandit

A late night hook-up that you met on tinder (or any "dating" app) and you don't want your roommates to see them because they are well below your usual standards. So you sneak them in through the back door.

Hey Rob! We heard the back door bandit sneak in last night. How was she? Did this one have both legs?

Leprechaun's Back Door

When a woman inserts glitter into her anus and then farts upon a man's face.

Tim: Dude, have you been to a strip club? You have glitter all over your face!

Back Lash Wave

The swirling air of the wind scar that circles an enemies demonic aura and hurls it right back at them with such great force that the enemy is forced to be demolished and hurled into the netherworld.

The back lash wave can only be observed on IunYasha.
