And, I vote for "rude" also! Some of these people are so 'not nice'! They need to know that their behavior is unacceptable, and rude is the best word to express it.
I miss that "gr" that was taken from us. I used that in so many situations..
" Dude can I have some free things"..........omg gr-boot magic
" DC in the middle of a game....................omg gr
" I'm reporting you for no good reason".......omg gr
"BSOD..................................................omg gr gr
"I swear this is 3 star firework magic".........omg gr, cheated again
See how useful the word gr is?
