A group of people (usually involves on gay guy who is a tool the rest are girls) who just go to parties to which they are never invited to but hear of from a friend and somehow leech their way in. They add no social contributions to the event but instead just smoke all the weed, drink all the booze eat or waste all the food and just have sex and destroy shit. They are dumb as fuck and to connected to social media to ever put their phones down because they have to be more anti social and tweet or facebook or whatever. Finally they are just downright sluts with no morals or bodily integrity and again are dumber than a bag of hammers
York Region girls, most of them are in a gyaldem.
