Juking is done all over the world but it is usually only referred to "juking" in the Chicago area.
Juking is a form of grinding but juking is when the male & female, or female & female, are facing front to front while grinding is when the female's butt is to the male's front.
Many believe it is a form of dancing while others just think it's dry sex.
It is done in a motion of shaking your ass around while the guy holds on to you & follows your rhythm.
