Just an idle question really. In Judo, there is a rule that in a competition you cannot be really smelly. This was to combat those who would eat garlic, onions, not wash their suit & generally just stink to put off their opponents. I've never encountered this in competitions myself (although occasionally some anonymous wanker drops one in training). Anyone ever encounter a really rank opponent in a competition. Do the same rules apply in BJJ? Ever tried having really bad breath to try and sub your opponent just by breathing?
