look up any word, like cunt:
When a conversation is so loud and drunken that bystanders cannot ascertain in what language it is being conducted, it is said to be spoken in the Language of Fuck.
"Did you hear those two assholes last night?"

"Yeah, kept me up for an hour, what were they speaking, Arabic?"

"Sounded like the Language of Fuck to me..."
