SMS language/txtspk for "Gay Little Smirk".

Used in SMS language (texting language) to express an individual's true reaction to a humorous text message. This abbreviation is a more accurate alternative to writing "lol". Clearly, he/she is not laughing out loud in a literal sense, but is instead staring at his/her mobile phone while brandishing a gay little smirk.

(In a texting conversation)

AJ: Dude, she is seriously smokin' hot. I would be her on-demand asshole licker. Let me explain to you what that entails. I would lick her asshole on-demand.
