I don't know how to spell it, I tried searching on google for fufu foofoo pfufu pfoofoo pfoofu foofu pufu poofoo fuful pooful puful etc.. and poofoo got the most hits, but no real definition or origin.

You may have heard Carl Baron mention it on his DVD. Now maybe it's just me but I think it comes from football valve, but my girlfriend thinks it's much older than footballs but I don't know if she knows what she's talking about anyway.

Can anyone share any insight?

poo poo valve?

yeah its a weird one
i first heard it in the carl baron dvd too
my bro explained it to me, i can't quite remember
but its a colloquial term for a nothingness inside you
like when you are 'winded' after running etc
ill see if i can find my aussie slang dictionary

burst your cafoufal value?

I use to hear it regularly when I was a kid (approx 30 years ago)
Yeah, it usually meant you were out of wind (steam? heheh) or was sometimes used as a warning when lifting heavy stuff
"careful, you'll break your poofoo valve"
