Well a/s/l is an abbreviation in internet slang, according to wikipedia.
All I know is, that it's short for a
ocation, and it's how fat old guys get in touch with someone. Typical usage follows:
CommonNewb: Hi! Can someone boost me through nightmare?
ImAnOldGuy: hi CommonNewb! a/s/l?
CommonNewb: Well, I'm a 16 year old guy from Germany
ImAnOldGuy: nvm d00d
Edit: Oh year, and I love the dramatic zoom on the smiley in the third picture
Apart from that, the idea that the basilisks deadly gaze should be transportable via a computer is really funny.
However, this does raise a question: can smileys or fonts be deadly? Should we fear a new messenger virus with a smiley resembling a ring going around?
