Noun (plural). It means the sort of assholes who try to get their advert accepted as an Urban Dictionary definition. The sort of people who try to get a flattering definition accepted, of themselves if they haven't got any friends, or of some female if they think it will help them get into her knickers. These are the same sort of people who will attempt to get an unflattering description of someone accepted as a definition because that person has
pissed them off and they are too weak or chicken shit to do anything else about it.
In short they are people who are weak, ineffectual and friendless, a failed evolutionary experiment that should be consigned to
Mother Nature's rubbish dump. Incidentally the noun singular (Winky) is also the name given to a minutely small penis - says it all really.
