When two models or a director/organiser and a model from a fashion show, shoot or other, get it together. This is either in public or behind closed doors. The term Originated in Leeds after a University semi professional fashion show, filled with mo mance, spun out of control and made the local papers.
So did you hear about the Leeds R.A.G. fashion show? Mo mance central.

Man, those two models are so Mo mancing at the moment.

That director and model are having an inappropriate mo mance.
