A seat very high up in a stadium or theater, as for a sporting event, musical performance, play, etc., which typically costs less money but has a restricted view. "Nosebleed" refers jocularly to the effects of extremely high altitudes on the body, which can often cause nasal hemorrhaging, among other symptoms. I wish you wouldn't be so stingy when you're buying tickets. I'm sick of watching football games in the nosebleed seats!I waited too long to get tickets to the concert, so all that was left was a nosebleed seat way in the back.
