Somebody who says they're there for you, but never is. They say forever but really they mean until they find somebody better. They might or might not keep your secrets. They're going to choose a boyfriend or girlfriend over you. If they are of the opposite sex, things will get very complicated. Best friends are bullshit.
My best friend ditched me to hangout with her boyfriend last night, I'm sure she'll be replacing me any day now.

Hey why is the bathroom covered in blood ?
Sorry I just had a best buy. Fuck does my ass hurt. This is worse than choir practice.
Next time you will know better than to eat so much cheap junk food.
Hey can I borrow a tampon ? I know I will be paying for my best buy for the next week.
Let me see..... wow that best buy tore your asshole right up ! Here take the pack.

The phenomenon of one's "stomach dropping," signaling an impending fecal explosion within mere seconds, forcing the victim to make a hasty exit to the nearest toilet. Entomology of the phrase originates due to the fact that this first happened to the wordsmith's father while he was in line at Best Buy, and was forced to abandon his purchase.
"I had the worst Bet Buy yesterday, it was awful."
"Get out of my way, I've got like 15 seconds until I Best Buy in my pants."
"Get out of my way, I've got like 15 seconds until I Best Buy in my pants."
