Feel free to contribute to this ongoing project. I'm sure I'm missing something as I'm doing this from memory and can't be bothered to read through tons of old posts.
Sold! - an expression of delight used to indicate when one has successfully convinced someone to purchase an album. Always written with at least one exclamation point.
Drunk thread - A thread posted while under the influence of alcohol, usually containing multiple spelling errors. These show up at least once a week.
Bodomites - rabid fans of Children of Bodom, known for greatly overrating that band and instigating flame wars and coming up with very stupid arguments.
In the gay way - A term used to express fanatical devotion to something.
17 - a number of mysterious significance, which shows up randomly in threads.
avatar - an identifying image, people have been known to drive others crazy by changing theirs on a regular basis.
signature - memorable quotes often end up being used in them.
ERIIWIRRDSS - a mangling of the word "weird" that first appeared in a drunk thread, used to describe the completely bizarre. (correct me on the proper spelling.)
Negura Bunget - Romanian black metal band heavily promoted by Royal Carnage.
staff pick of the week - the best album being reviewed in each batch of updates as determined by the RC writers. Most of these were heavily discussed on the forum at one point.
thrash metal terror - a term coined by Erik and Sorath to describe the intensity of thrash, especially their own.
living in the past - an insult used by Neal and others. Often written with the adjective fucking.
prog - abbreviation for progressive rock, a genre loved by many on the forum, though no one can agree on its proper definition. King Crimson is particularly revered by a few forum members.
Celtic Frost - BWD's dislike of them led to a particularly memorable thread and signature image.
gay forest - a picture of a colorful forest and a power-metal related inside joke.
phorest fotography - a nature appreciation thread containing some striking photographs taken by forum members.
GMD - General Music Discussion, an area of UM known for acts of idiocy. Threads from here and other places are often linked and mocked.
Iron Maiden - subject of RC's first review of a band's entire catalogue, and one everyone on the forum agrees on, with the notable exception of NAD (who ironically shares his name with Adrian Smith.)
tabs - according to one Bodomite, one must read them before reviewing an album.
Madder Mortem - the hysterical vocals of their lead singer caused RC's most infamous negative review and played a key role in a flame war. See also Atrox.
rhyming game - a bit of inspired nonsense designed as a way out of a flame war. New word every five posts.
threadjack - deliberately causing a thread to go off-topic. Happens in over 75% of threads.
melodic death - influential but now declining genre that still causes intense debates, especially In Flames and Arch Enemy.
NSBM - black metal subgenre whose ideological distinctions have led to massive differences of opinion, some people refuse to support such bands while others fervently defend their music and nationalistic (and often blatantly racist) overtones.
Goatsblood - depending on who you speak to, this band and Watchmaker are either visionaries or unlistenable noise, see the point-counterpoint review on the RC site.
Primal Fear - spam for a record release party by this Priest soundalike band led to the most disgusting threadjack on RC ever, which greatly upset said spammer.
horror movies - a favorite pastime of many forum members, particularly Japanese horror and zombie flicks.
porn - another favorite pastime of the forum. Many threadjacks result in sexually explicit discussion.
politics - another frequent non-metal discussion topic, many members of the forum are fiercely anti-Bush, but just like with music, there is little everyone can agree on.
band everyone can agree on - we haven't found one yet, and likely never will.
