Where I come from people mostly go ''SLAYERRRR".
Correct pronunciation; "FUKKEN SLAYERRRR"
Actually, try calling out "SLIPKNOT!!!" at an extreme metal gig. But only if you're big - I can't vouch for anyone's safety.
Lol, I'd have serious respect for anyone who dares that, regardless how big they are. The ensuing pit would be murder.
My band is sort of a jazz rock thing with a female vocalist, and we tend to book eclectic gigs. Our last show was with a punk band closing, who proceeded to get WAY drunk and wanted to play before us, to which I said no as the crowd (who were only about 25 people) was starting to get really drunk and a little violent and I just wanted to go home. People were pretty much just yelling at us while were setting up, and then we got a "PLAY SOME SLAYER!!!!!" right before our set, so I busted out the guitar line to "South of Heaven" on bass, and people clapped, got quiet and moved toward the stage. It was like someone flipped a switch. No problems the rest of the show, and we even stuck around to watch the punk band, who were good. Possibly the only time Slayer ever calmed an audience down. Thank you, Slayer, thank you.
