MFPOS 

Having inroduced 'FOBYAC' into to Urban Dictionary and wishing to retain somewhat of a theme, I now provide you with a second wonderful acronym, 'MFPOS'.

If, (when), used in open forum, calling someone a 'Mother Fucking Piece Of Shit' may provoke undue tension amongst those present, not least in the person towards whom 'MFPOS' has been directed, but again and with a degree of delight, once can openly verbally abuse a fellow human being, (perhaps one who is a complete tosser, whilst hiding securely behind the complete and total anonimity of these few choise letters........MFPOS!

Introduced subtly into every-day conversation, one may employ MFPOS in the following manner:

Covertly: "Excuse me, Sir, you're a MFPOS"
Enraged: "Oy, shithead, you're a MFPOS!!"
Questioning: "Tell me, are you a MFPOS?"

MMOSH 

Massively Multiplayer Outside Scavenger Hunt

A scavenger hunt that involves more than 20 people.

Normally started by friends with no prizes involved, fun is the main goal.

Items are only a small part of lists crazy acts are put on the list to such as drive through a drive-thru backwards.

Our school didn't like the idea of an MMOSH due to the fact that clayton put wedgie a freshman on the list.

Bros before MMOs

A phrase to remind long time close friends that friends come before MMO's (Massively multiplayer online games). The phrase is commonly used amongst gamers who have friends who may choose to play an MMO game rather than hang with their friends.

Friend 1 - Sunday is MW2 day this week?
Friend 2 - Yeah should be
Friend 3 - Sounds good to me
Friend 4 - If evening, then yeah
Friend 1 - It'll be around 4 or 5
Friend 4 - You said 6:30! I got 5v5 at 3:30
Friend 2 - Bros before MMOs dude
Friend 1 - No you said 6:30 later, check the time between updates, 6:30 now
Friend 4 - Checking Xfire times, 45 minutes ago you said Hoe1 was around at 4/5. It wasn't until 15 minutes later when that changed. So the time you posted must have been wrong
Friend 1 - Yamyamyamyamyamyamyamyamyam
Friend 4 - I say, Dr Watson
Friend 2 - Bro's before Hoe's
And now a newer version!
