Theres nothing wrong with being psyched, I myself enjoy BATB but the people who are like "FUCK J LAY HE RUINED MY BRACKET!!!!" OR "[INSERT NAME HERE] IS A SHITTY REFF!!!!!" are the ones who are annoying me. It's not like the people participating care that much.
By all means, get stoked on the tricks people are pulling and who's doing them and how consistent they are but don't treat this like a fucking sporting event.
