Becase they are BFFs.

Meanings Best Friend Forever, but has been made incredibly stupid and overrated, mainly by stupid commercials trying to be "hip".
10 years ago the term BFF meant best friends forever, now i shudder every time i hear it because of stupid commercials trying to be cool by interacting with the younger audiences, but failing miserably and making whatever their advertising look like shit.

big fucking faggot. commonly used as "last one to ______ is a big fucking faggot!" to replace the more sophomoric "last one to ______ is a rotten egg!".
