Yeah the morning after a few pints and a curry - when I stir up they just blast out and some can be right scorchers. Probably something to do next to what's in the gas from what you've eat along with the amount of gas and force it comes out. And sometimes they don't partially stink.
haha not recently but enjoy done before lol
