Something nasty people do when they are bored, have no life, or are really stupid. It's nasty because a lot of the time you never hear about it and people are way too PC to admit and are nice to you to your face, but spread nasty gossip behind your back. And you never know what happened when someone suddenly hates you for no reason or some people start threatening you for no reason. That's because some loser(s) with no life or brain decided to gossip because they're too stupid to have any hobbies, a real social life, or any shread of concience whatsoever.
Gossip is what happens before you get a knife in your back.
"You're a gossiping wench and I hope the toilet eats you next time you take one of your rauncy diareah shits"
"Get a new hobby, try nitting, cutting yourself just stop gossiping. It causes cancer."
