An emoticon used to alter the emotional content of a message so that it appears to have a different meaning than the sender's actual intentions.

Often, a decepticon is used to "soften the blow" of bad news or to veil a threat.

IM Conversation:

Boss: "If you don't work harder, there might have to be another round of layoffs :)"

Employee: "Were you really smiling when you typed that, or was that smiley a decepticon?"

Decepticon 

At the climax of sexual intercourse pretend that you're going to aim for the mouth when depositing your load, but instead hit em in the eye and say "more than meets the eye." Then proceed to "roll out!" As an option, you can choose to wear a transformer mask w/ voice changer.

My ex-girlfriend is pissed that I gave her a decepticon. Now she has a lazy eye. I had to roll out fast.

You know when you see a girl from a distance and she looks pretty hot, but the ugly factor increases the closer you get.

(from a distance...)
Friend 1: Dude! Check her out!
Friend 2: Yeah, not bad!
(the closer they get...)
Friend 1: Yo dude, my bad!
Friend 2: No prob, she's a decepticon!

Decepticon 

A homosexual individual (typically male), who presents or misrepresents himself as a heterosexual. This individual has the innate ability to avoid detection by a heterosexual individual's gaydar (a.k.a "stealthing it").

I always thought my roommate of five years was a real man's man. Turns out he actually was another man's man. I should have known he was a decepticon!
