open mouth kiss 

Open mouth kissing is a simple kiss,
With or without the slight use of the tongue.
It is normally a short, meaningful kiss.
This kiss is simply a step ahead of the average Peck
And a step below a full blown Makeout Session
NOTE : An open mouth kiss is exactly what it says
A kiss on the lips, with mouths slightly opened
To decrease awkward lip tightness for a more relaxing,
Enjoyable kiss.

Open Mouth Kiss :
- Slightly opened lips

- Very little use of tongue, if any
- No longer than 5 seconds

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."

open mouth, insert foot 

when one slips up in a conversation and eat their own words.

Luke told Jen that she hates Canadians. Jen then told Luke that she is actually a Canadian. Open mouth, insert foot.

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 Mouth Breather 

Open Mouth Breather - An individual that breathes through their mouth when not exerted. The individual appears to be, and ususally is, perpetually confused, not very bright, an idiot.

You see someone from Wisconsin driving along. As you pass them you see their profile and their mouth is wide open, an Open Mouth Breather. Although they are looking straight ahead, they don't see traffic stopping and slam their brakes on at the last moment. This is an example of an OMB (Open Mouth Breather)

the always open mouth

The Always Open Mouth is the third album by the Colorado band Fear Before the March of Flames. It was released on Tuesday, September 19th, 2006.

The album marks a very different sound for Fear Before the March of Flames: whereas their previous two albums concentrated much more on raw, powerful Hardcore music, this album contains a much more experimental side, such as more emphasis on antiphony between the lead singer and guitarist; a considerable lesser amount of screaming; layered guitar chords (a second guitarist was added to the band before the recording of this album); and many electronic sounds used with heavily-distorted or otherwise-effected guitars and synthesizers, or sequencers and drum machines, giving it a more Industrial feel. As a result, it is not as hard or fast as their previous two albums, but instead, is more experimental and well-crafted.

The Always Open Mouth is so different from the rest of Fear Before's albums, yet so amazing.

Dream with one's mouth open

The act of verbally sharing or expressing dreams, ideals, or improbable plans with others as if they had some validity to them. An extension of the proverb "counting chickens before they have hatched", this phrase is the equivalent to not only counting the chickens, but generously distributing them out to friends, family, and acquaintances.

*Examples of Dream with one's mouth open.

A: My band is getting a really good response at facebook and we're getting more and more people following us at twitter. It's just matter of time before we're picked up by a label so we can release our CD and go on tour.
B: Stop dreaming with your mouth open. It's just sad...

A: Ooh, I'm going to be hooking up with someone tonight at the party.
B: Dude, didn't your mother ever tell you not to dream with your mouth open?

A: So she told me that she was talking to a massive client and that we should be getting some decent work soon.
B: Yeah, and she tends to dream with her mouth open. I wouldn't hold your breath.
