FOFN 

Acronym - for 'Fuck Off For Now'. Used to end a text conversation when you want it to finish but do not intend to be rude. FOFN is a tongue-in-cheek way of saying: "this conversation is over for now."

VERY IMPORTANT:
FOFN is the FINAL word. Once used, the conversation is OVER.

SILENCE. The conversation is over!
