Open Mouth Syndrome

When somebody's jaw always seems to be hanging down, mouth is always involuntarily open, etc. Douchebags, dumbasses and hoodrats make up most of the infected population with Open Mouth Syndrome.

Pat- "That douchebag TJ never closes his mouth. Always looks like he's open for business and deepthroat sessions. Guess he's just retarded."

Jon- "Yeah dude that dumbfuck has Open Mouth Syndrome."

I told Sam I'd bang Darren's wife 'cause she is so hot, when Darren was actually behind me the whole time. I practically opened my mouth and inserted my foot there.

open world pvp

PVP that takes place in an Open World. Many instances of PVP take place inside instances, zones created for the PVP in which set numbers of players fight in their own personal map until a victory condition is set and that copy of the map goes away. By contrast the Open World is a non-unique setting that you and other players can freely move around, so Open World PvP contains a lot of unpredictability and often starts with randomly encountering hostile players.

I'm tired of these arena matches, let's go to hostile territory and do some Open World PVP.
