A hardcore fag: generally disliked by many: one that words can not describe
Faggerlets are not gay people, or even related to "faggot", and the homosexual meaning of "faggot".
Faggerlets are the annoying kids who remind the teacher you had homework.
"Hey, didn't we have homework due?
SHUT UP, you faggerlet."
"Gosh, they're so annoying...
Oh, so they're a faggerlet?"
