To whine or complain in an annoying manner. Note that this is a REAL word, and that it's different from all the idiots who posted "winge." I'm shocked that "winge" was picked as a word of the day.
Someone that complains by stealth in order to undermine their victims.
A person that uses something you've told them in confidence to get at you behind your back.
Someone that deliberately puts shit on you for personal gain.
The nasty emo step-child of nu metal. It is the bandstrying to bridge the gap between Mudvayne and Madonna. They think they can be emotive and whiny while still being rock. They are wrong.
