Having been in a high-school jelly fight (damn but that was fun) I can tell you that jelly may be slippery to start with, but once it starts drying on your skin/clothes/hair it's one of the *stickiest*, least pleasant feeling substances known to man. How anyone can find that romantic is beyond me. Indeed, I could see it making sex a highly painful and potentially dangerous activity...
