HAVE FUN

Some people prefer cryptic initialisms over ASCII art for expressing online emotions and other things that they don't wish to express in plain English sentences. (These abbreviations are sometimes mistakenly called "acronyms", but that properly refers only to initials that are pronounced as words, like "NATO".) Here are a few of the ones you might encounter:
AFAIC
As far as I'm concerned
AFAICT
As far as I can tell
A/S/L
Age/Sex/Location (asked in chat rooms)
BCNU
Be seeing you
BRB
Be right back
FOAD
F*** off and die
*g*
Grin
GD&R
Grinning, ducking, and running
HAND
Have a nice day
IANAL
I am not a lawyer
LL&P
LOL
Laughing out loud
ROFL
Rolling on floor laughing
TTFN
Ta ta for now
YMMV
Your mileage may vary
