backup brain

When you are high on the reefer, and another brain which thinks differently than your normal brain takes over

Wow, I would have never thought that without my backup brain.

Backup friend 

A person who is someone you know and are "friends" with, but isnt treated like a friend. You are treated like an acquaintence. This is a person one only talks to when their actual friends are away. The person who is the back-up friend is treated poorly and is usually someone who doesnt have a lot of friends or gets a lot of dates. The backup friend is someone who gets the short end of the stick when it comes to friendship. The person who sees you as a backup friend doesnt care about you and isnt concerned with any part of you as long as you are someone they can come to when they want to converse with someone when their real friends have disappeared.

You see someone who you've been friends with who you havent seen in some time, but you want to invite them out for a drink or dinner and they all of a sudden ignore you, yet they were really chatty with you several months earlier. A clear sign you are a backup friend.

backup bitch

The girl a guy keeps leading on even if not entirely interested in her, as an ego boost or backup just in case the girl he really wants turns him down. Usually the girl he leads on has a crush on him, and is okay with being lead on, because she's still getting his attention.

She really liked him, but she was only his backup bitch.

Deadly Semen Backup 

Deadly semen backup, or as doctors call it DSB, is a condition brought on by extended male abstinence , frequently combined with the absence of masturbation , resulting in massive loads of semen accumulating in the lower pelvis area, and travelling up to the brain and central nervous system. The accumulated semen interferes with the operation of the brain and can result in death. The condition can only be remedied by immediate and continued application of oral stimulation and vaginal stimulation.

Doctor, he apparently lost conscious in is car and swerved off the road. After preliminary tests it seems to be "Deadly Semen Backup" , or DSB . I hope its not to late to get the revival team in here to drain it.

bacouple 

A Japanese slang portmanteau of the words baka and couple (couple is pronounced kappuru in Japanese).

Used to refer to a couple who, prior to being together, at least had the sense of shame to not flirt with each other in public and embarrass people they know or gross out everyone else.

"Jack and Jane are such a bacouple, wearing those silly matching clothes and flirting around in the middle of a shopping mall. Let's pretend we don't know them."

TP Backup

Something that is used to wipe the ass when conventional toilet paper is not available. Most often, the need for TP Backup is when the person pooping misjudges the amout of toilet available at the time. Hand towels, magazine pages and discarded tissue are often useful TP Backup.

When the toilet paper ran out, I realized that there was still more poop to clean off my ass. I looked around the bathroom and saw a Cabbage Patch Doll, I had to use it as TP Backup , or else i'd be in big trouble later.
