Buon For Life, "buon" meaning sad.

Group founded by a USC PharmD student in 2010.
BFL people often get together and drink during their down time, most often vodka and tequila. They also listen to music that reminds them that they'll never be happy. Being BFL is not a status, a mood or a phase, it's a way of life. No one can really understand them because they are a different kind of people.

People who are bfl and who finally start seeing a brighter side to life cannot quit BFL unless they are kicked out by unanimous vote because as the name indicates it, once your are BFL, you're in it FOR LIFE.

Blocked for Life

Can be used for several things
1) Phone Numbers
2) Instagram
3) Any other Social Media Site that allows people to stalk you tremendously.

If someone sends you "BFL" then you are most likely a creep, weirdo, both, or pervert. Of course I can believe any of those.
