Yeah Maki, explain the whole thing out with as much of a straight face as you can muster, I mean the whole thing is unique, and if your child is at least showing passion with this, I really don't think it should be stifled... it's an homage to something the other kids will be familiar with, will get a kick out of, and really, it's pretty unique for a 6 year old to do... I go through alot of this currently with my 7 year old son and his "imaginative time" in school. I've had meetings. V:O) It's not like it's "beans beans the majikal fruit" time, it's an armpit fart. the kids will love it. And the Parents should embrace it for the funny it is...but you know the drill.
