Stealthfart 

A silent and odourless gassy emision coming out from where the sun doesn´t shine, often producing a temperature increase in your underwear. Specilly useful to heat pants and trousers in cold, overcrowded and confined environments.

- Man, is so freaking cold here I can see my breath!
- Yeah, thank god i stealthfarted, at least my butt and weenie are warm now.

Uber Stealthcast 

An Uber Stealthcast is a Stealthcast that is launched with absolutely no promotional efforts.

Whereas a Stealthcast will typically have one type of notice, typically a singular post via Twitter, an Uber Stealthcast will have no notice.

Specifically, it is a very low-key webcast, typically catering to a small audience that may be in the IRC chat room associated with a video feed.

The phrase was started by YouTube and uStream content creator, Alfred, who wanted to reciprocate entertaining video content, via a webcast, for those who were tirelessly monitoring his IRC chat room.

"Holy cow, I didn't even know he was doing a Stealthcast, I didn't see a post on Twitter!"
"That's correct, he didn't post one. It's an Uber Stealthcast"

stealth fart

A ninja fart that has been held in and then is strategically released right as you hear someone else close by rip a big one. That way, EVERYONE, except you, will just think it is ONE HUGE STINKY FART from the other guy!

Since I work with Old Ass Blaster, and only release stealth farts, no one even realizes what a fartist I am.

Stealth fart

This is when someone else near you farts and gets caught and you fart so that everyone else thinks it was the other person again.

Stealthcast 

A live, unscheduled webcast (note: webcasts are sometimes referred to as streams) that is initiated with minimal promotional efforts, such as a single Twitter post.

A stealthcast allows for a highly personalized and interactive session with a sparse audience. Participants are typically those individuals that are persistently logged into an IRC chat room associated with a specific webcast (enjoying ongoing chats while also hoping to catch a stealthcast), as well as those who joined based on viewing the minimal promotion, either by polling a website, using a third party program for alerts, or by receiving notifications via their mobile device.

The phrase 'stealthcast' was started by YouTube and uStream content creator, Alfred, who wanted to reciprocate a 'thank you' to those monitoring his IRC chat room with a live webcast while also having a personal, interactive session with a small and selective audience.

Via Twitter: "Stealthcast is now in progress. WATCH: {URL}"

Stealth Fart

This is when you hold in a fart for just enough time, then let it out very strategically, so then it comes out silent.

Hey man, I had to stealth fart earlier, it was nasty.
