I was at a very enjoyable gig last night but there was a woman behind me "whooping" in between every song and even during some of the special "pauses" etc.

I've got to confess it was a bit irritating at times but, instead of complaining, I gave the occasional "whoop" back.

There are other annoying things at gigs, of course, including talking during songs, singing during the verses as opposed to the chorus, exiting and entering while the artist is in the middle of the song, mobile phone lights and filming etc and much more.

"Whooping" probably is just slightly less worse than clapping out of time, in my opinion.

Where about in the "annoyance spectrum" would you place it yourselves?
