The term "Skonker" is not widely used. A small group of friends who currently reside in Oakville, Ontario, use the term Skonker in replacement of "Skank" or "Slut". Sometimes a shorter version of Skonker is used, which is "Skonk".
Furthermore, Skonker is a term used to describe a certain type of girl. Skonker describes sexual promiscuity and can also be used to represent a girl of a lower socio-economic class or one who doesn't present herself in a well manner.
