Based on the term "Romance". It is fundamentaly based on the act of using the opposite sex, without any sexual relations. Flirting is a great way to keep a show-mance without the actual act of fornification. Can be used to decribe the act of "show-mancing" or the actual person "the show-mance".
Dude, I'm going to show-mance that chick to buy me drinks all night.

Dude, I'll intro you to the show-mance tonight. She's a real douche.
