If the fans have a right to yell, cheer, applaud, chant "this is awesome", etc. then they also have the right to chant "boring". Let's take the Cena promo since that seems to be the catalyst for this post. Fans for the most part stay quiet when someone is talking except to boo or cheer so how can the brass know something isn't working. They will think the fans are just listening. When they start chanting BORING then the brass knows something needs to be fixed. The same goes for a match. If the fans are not entertained by a match they have just as much a right to chant BORING as they do to Boo/Cheer or "pop" for a big move. That right doesn't make a difference if it's a women's match or a men's wrestling match. If they are not being entertained then they can chant boring. They paid the money to be entertained. That usually means the match has lasted too long and they should end the match soon and work on timing of future matches
