I thought it was a great idea for a topic to explain some of the naming conventions and to throw open the floor for other contributions from our readers. I'll also go some way into starting a kind of PvP glossary. I've been scouring the official forums and the like for threads where people ask questions of this nature to come up with a compendium of terminology to help you all out.
Now, a caveat -- and it's a big one. Particularly with the Arena composition names, there are some really bizarre ones out there. Some like the African Turtle Cleave have become pretty ubiquitous, but some are still very obscure. Others are really rather unsavory, and those aren't going to be up here.
If you add new ones in the comments and you can put in some links to prove their validity, I'll edit them into the piece, so get involved. And if there are terms I miss, ask; they can be edited in as well. I'm not even going to try to explain where some of the stranger ones come from; if you want to, then go for it!
Arena composition names
Many compositions crop up more than once under different names. Don't worry -- it's normal that people can't make their minds up! And some may relate to older comps that were played more regularly in earlier seasons.
Acronym composition names
These are some of the more prolific, the more obvious to work out, and the more freely invented comp names. Why? Because it's a hell of a lot easier to say "RMP" than it is to say "Rogue Mage Priest"! The initial list excludes ones I don't hear mentioned regularly. Most are very obvious, some more obscure.
RMP rogue, mage, priest
RLS rogue, (war)lock, shaman (restoration)
MLS mage, lock, shaman (restoration)
MLP mage, lock, priest
WLS warrior, lock, shaman (restoration)
PHD or PHDK paladin (holy), hunter, DK
FMP feral druid, mage, priest
LSD lock, elemental shaman, restoration druid
LSD2 lock, restoration shaman, balance druid
RRP retribution paladin, rogue, priest (usually healing, could equally be a paladin)
KFC Kung-Fu Cleave -- warrior, hunter, healer
TSG DK, warrior, healer
Cleave composition names
Firstly, it's good to note that a "cleave" was generally considered to be two melee players and a healer; however, it seems that cleave compositions can now be just about anything right now. Comp names like Wizard Cleave or Harry Potter Cleave particularly fly in the face of the melee roots of the term, and I'd say it now means a team with 2 DPSers and a healer.
African Turtle Cleave warrior (protection), hunter, healer
Beast Cleave hunter, enhancement shaman, paladin (holy)
Jungle Cleave hunter, druid (feral), healer
Kung Fu Cleave warrior, hunter, healer
Lumberjack Cleave warrior, warrior, paladin (holy)
Thug Cleave rogue, hunter, healer
Shadow Cleave 'lock, DK (unholy), healer
Kitty Cleave druid (feral), warrior, paladin (holy)
Spicy Chicken Cleave mage (fire), druid (balance), healer
Man Cleave warrior (arms), warrior (protection), paladin (holy)
Wizard Cleave 'lock, mage, priest or other healer
Harry Potter Cleave 'lock, mage, priest, or mage, mage, priest
Ebola Cleave DK (unholy), druid (feral), healer
Turbo Cleave shaman (enhancement), DK or warrior, druid (restoration)
Mongolian Earthworm Cleave shaman (enhancement), druid (balance), priest
Kanye West Cleave rogue, rogue/DK, shaman, or any composition with a lot of interrupts! This name made me laugh; it's not very common, but I liked it!
Play composition names
These usually relate to caster teams, and unlike the cleave composition names, this has remained mostly the case. I haven't come across any of these in my time that don't include shadow priests; if you have, let me know.
Shadowplay 'lock, priest (shadow), shaman (restoration)
Shatterplay mage (frost), priest (shadow), shaman (restoration)
Fireplay mage (fire), priest (shadow), shaman (restoration)
Owlplay druid (balance), priest (shadow), shaman (restoration)
Other composition names
These fall into none of the above categories and are few and far between. They're among the sillier but more creative comp names. If you know of any, drop me a comment with a link or two to prove their validity.
Dancing with the stars rogue, druid (balance), healer
Spicy Chicken mage (fire), druid (balance), healer
General PvP glossary
This was inspired by someone asking me what a "peel" was on Twitter when I told them to get their melee to peel for them more when they were being trained as a healer. A lot of it will be things more experienced players know already. If you have things to add or things you'd like to know the meaning of, tell me in the comments.
