DDF 

DDF or Daily Dose of Frank
(Original - Dnevna doza Franje (Croatian))
For when you have a friend in group who just has random outbursts of unrelated, fairly stupid comments or jokes and after a while you become used to it and call such phenomenon - DDF.

It's also appliable for when someone else has stupid remark and you call it DDF in respect to Franjo, the ultimate redneck.
(in original his name is Franjo which is croatian for Frank - and therefore "Daily Dose of Frank")

Out of the blue, unrelated he says something like

Frank: "If someone threatened you with a gun, what would you do? - suck him off"
Everyone: "hahaha, DDF!"
-----------------------------
Original:
Franjo: "da ti neko prijeti s pištoljom kaj bi mu napravil ? - popušil bi mu kurac"
Svi: "Hahaha, DDF!"
------------------------------
Frank: "Shit on me my pidgeons, shit!"
(Original Franjo: "Serite po meni golubovi moji, serite")
