When several male workmates engage in a game of "Farandos cum party". This is where they line up and take turns cock slapping one unfortunate colleague who is known as the 'farandos'. The winner is the last person to cum on his face. The loser, as a penalty, must "clear up the mess" with his tongue.
Farfanoogin is the way a moron pronounces Fahrvergnügen, a German neologism meaning "driving enjoyment." It is often parodied or used when the speaker does not speak German, but wants to use a German word.
Moron: "Did you see that German guy? He's a real farfanoogin if you no what I mean."
Normal person: "I don't even know who you are. Why are you in my house?"
