I was really just giving Joe a hard time, because he is "The Etiquette Police", and he likes to remind me of what a sorry excuse for a martial artist I am when I have occasional lapses in etiquette memory. Shihan was standing there when this incident happened, and he said if there was such an etiquette, then he was in big trouble!
We do have a few belt rules in our dojo, but I guess tasteful displays of affection are acceptable. However, if you asked the students from the kid's class, they might disagree. I have a feeling they would probably think it was icky, belt or not!
Roseberry's Sho-Rei-Shobu-Kan belt etiquette:
Never let your belt touch the floor.
Never throw your belt.
Never slap or choke other students with your belt.
Do not carry your belt around your neck.
Do not wash your belt.
Do not wear your belt outside of the dojo.
Remove your belt before eating, cleaning, etc.
(Obviously the first one doesn't apply to when your belt touches the floor while training, and I'm not sure what "etc" is, but I thought it was "kissing" ;)
