A flamboni is when a man takes a woman's bloody recently used tampon and drills it up his own ass using his index finger, then craps it back into the woman's mouth.
This bitch wanted me to eat her out on the rag so I gave her a Flamboni so she could taste that shit herself.

Acronym for “I Feel A Shit Coming On”. Stating “IFASCO” in public is a polite way of alerting others that it is imminent you will need to excuse yourself to take a shit; While you may not need to immediately defecate, it is undeniable a shit is on it’s way.
