BFUC

Acronym standing for "best friend until college", or "best friend until cremation" for people who will be friends until death. It is an alternative to the hugely overused BFF and gives you an excuse to say the f-word, so you should say it.

Tom: Wow, you are soooo cool.
Rob: Really?
Tom: Yes. you are definitely my BFF....no...YOU ARE MY BFUC.
