Had an incident today (in a match that got very heated later!) that I've not seen before. Two players square up to each other following some "afters" that didn't look like much to me, and while forehead to forehead, one sticks out his tongue and attempts to lick the face of the other player. I eventually seperated them and put them both in the book for AA, but didn't really know if licking someone should have come with a greater penalty!
