Rosenbomb

A series of untoward events occurring in an office, business, or department, thereby resulting in utter chaos. Considered synonymous with clusterfuck and FUBAR.

Lawyer #1: I just walked past our conference room. What a mess! There were books strewn everywhere. It looks like a bomb went off in there. What happened?
Lawyer #2: There was some serious contractual negotiations going on in there with the union this morning. You didn't hear the yelling and screaming?
Lawyer #1: Aha. Is that why Attorney Rosen was flown in from the main office...to ignite a Rosenbomb to facilitate discussion?

Rosenborg

Widely popoular Norwegian football team, from the town of Trondheim. Since they tend to win the national league every year, they join the UEFA's champion league tournament as the only Norwegian team, and thus they have supporters from all over Norway and Scandinavia. They play in black and white and their home stadium is called Lerkendal.
By football I mean the sport where 2x11 players actually kick the ball with their feet, not the Yankee version of rugby, where they hardly ever touch the ball with their feet.

Jeg er Rosenborg tilhenger! (I am a Rosenborg fan)

A rosenbourg piece is a collateral chomp of the 2.9 x 6.4, which subsequently equals Duncan Haslam, who is a very annoying Rosenbourg piece.

Sam : Go away Duncan!!!!!
Chris : Yeah, stop being such a rosenbourg piece you schlamp!!!!
Duncan : merioptiopmontyo...........
