When higher belts/more skilful teammates are 80% of the way to closing up a sub, it does get pretty fun to go, "Any white belt can do a [insert submission I'm gonna be tapping to in the next 3 seconds] bitch! You REALLY wanna finish with that??"
Note: This has a low but sure success rate - sometimes guys will really let go and finish with something more spectacular than a triangle or armbar. Needless to say, only do this with dudes who can wipe you out with their jits, or you'll just be a douche.
