SF is a black guy who's dream is to become a rapper. Nobody know's if he's an incel but his behavior is VERY suspicious. Calling people "chad" and calls himself a incel while he calls his friend TKF is a gigachad 'cause his friend dated 4 girls and he's dated NONE. The reason why we don't know this is because he always memes and he is never really serious. He usually ends plurals with "z" for his rapping future.

omg that guy always jokes about incels he's such an SF
