Navikwanzaka 

n. Holiday event which celebrates the longstanding traditions of Christmas, Hanukkah, and Kwanzaa. Festivities include Karoake, caroling, drinking adult beverages from sacred ice shot glasses, and games of chance. Gifts are forbidden unless won through successful gambling ventures, or by sheer force. Wrestling, Football, or Mixed Martial Arts are optional but encouraged as part of the total Navikwanzaka experience. Lamenting past broken romantic relationships, calling ex-spouses/girlfriends/boyfriends, and inquiring as to the nature of the caller's inadequacies is usually part of the great Navikwanzaka tradition.

Nehemiah: "Hey Jebediah, Where is Navikwanzaka being held at this year?"
Jebediah: "Two furlongs past the old mill, at the Pilsner's brewery."
(1843 Excerpt from the earliest known writings describing the first Navikwanzaka... The first event, allegedly was a barn-burner, but no one other than several small farm animals was injured in the celebration.)

grebo 

West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.

Some grebo passed with Sabbath playing on his stereo.
The Poppies are at no. 17? God, a grebo band in the charts!
They're playing nu-metal now, bloody grebos!
