1.
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."

FOFN is the FINAL word. Once used, the conversation is OVER.
Jimmy (texting)

Kev

Jimmy
FOFN

SILENCE. The conversation is over!
