someone who makes you feel constantly high on life, someone who makes you laugh uncontrollably for long periods of time, someone who provides you with the best inside jokes, someone who would be willing to skip down the hallways with you screaming, just to make people stare. best friend forever.

Black Friday Friend. The person you are next to in line that you chat up during your wait before the doors open. The conversation usually involves some sharing of personal information or previous Black Friday experiences. Your BFF can give you some useful shopping tips if they are a seasoned Black Friday shopper. Note: Once the doors open, your BFF may become an adversary.
In line at Wal-Mart on Black Friday my BFF told me the exact location of the 40 inch LED TVs on sale for a hundred bucks. After the doors opened we both raced for them and I punched her in the head as she reached for the last the set.

Many of these definitions make sense to me, especially 'best friends forever' as the probably original genesis. Albeit, the word BFF is also the name of a mossy rock / abstract pop music band.
