Oh I have a few.. they've probably already been mentioned though.

-People who try to cut in line at GA shows. If i've been waiting outside for some odd hours, don't get mad at me and try to come and cut in the line.

-Drunk people. You're waisting money and you look like a jackass

-People who complain the whole time at GA shows. Yes, we know it's hot but you agreed to come knowing it was a ga show. Get over it.

-People who smell like B.O. at Ga shows or otherwise. Use some hygiene please.

-People who are singing so loud, I can't hear the artist. We know you love the music and know all the words but I did not spend x amount of money to hear you sing.

-Slutty people. It will get you nowhere 98% of the time and yeah, you look like a fool.

-If your mad tall, and there are chairs, have some decency to sit down especially if you're in the first few rows.
