when a guy is at dinner and gets up to say goodbye, he stands up and reaches over the table to hug someone, and he inadvertently places his cannon within one inch of someone (who is still sitting down) at the table's face. the backfire-ee, if you will, then sharply turns their head not knowing their is a cannon pointed right at their face, and then proceeds to make full blown facial contact with the shaft and the ballbag of the backfire-er

Someone who used to be a potential girlfriend/boyfriend, but no longer is.
