Your best friend's girlfriend 

The girl that your best friend is dating, who is obligated to be a total bitch because of some subliminary life cliche. She will be clingy, possessive, and controlling, giving you little to no bro-time.

You and other friends will be forced to accept her into your social circle, but will talk mass loads of shit on her whenever you get the chance.

Your friend and your best friend's girlfriend-

"Hey bro, you still drinking with us this weekend?"

"Can't dude, I have to hang out with Carly."

"But broski, you've hung out with her everyday for six days now- Whatever, just bring her with."

"She doesn't want too, dude, sorry."
