I wish I could amend this node and change the title to ARG! but I'll stick with
arg.
arg is a statement of annoyance. People could say arg in any many situations but to save everyone time I'll give you my top 5:
At work and the boss is around so you cannot play on Everything2.
The DVD you just rented from Blockbuster is so scratched that it won't play!
I just ran out of cigarettes ARG!
This can be used also for alcohol and drugs too
CowboyNeal is chasing after you with Kurt The Pope's signature card trying his best to stamp you.
However, arg is probably used most in this situation, at least for most internet couch potato's... goatse.cx ARG!
Another statement of annoyance that I like as well as arg is Grrr!
