In the lingo and culture of pimping, “fagged off” means when a ho (prostitute) leaves a pimp for another pimp. Primarily used by pimps in the first person.
I put that wet dog of a bitch Annie on the blade barefoot, and the bitch done fagged off after her first date.
''He just flagged me off'
''You mean flipped me off you utter cretin rachel''
''No its flagged off''
''No, that isnt a thing, flagged off is a term wrongly used by mongs meaning flipped off"
