You know what it’s like. You are going around minding your own business and suddenly some old dude stops right in front of you, says ‘You is are American yes?’ and BAM! hits you with a chain of microflatulisms, pit, pit, pufffff , prhoooaaaaah…I don’t know about you but I’ve just about had it with these people.
Or when they come up and ask, “You Irish?” then start doing River Dance and going pit pit puffff, prhoooaaaah. Boy those Michael Flatulisms really get on my wick. 
It’s the SBD’s* you have to watch out for. Give them the ten second rule.
Silent but deadly (farts)
I hope you aren’t heaping the polite test farters in with the rest.
I’m heaping em all in together.

What about microshartism? I think it is likely nastier than microflatulism. I think such a lofty topic deserves its own thread.
I’m all about macroflatulism. I’ll clear a room when need be.
Hmmmm 
More sea urchins. Transform them poofy wee poots into trouser-ripping BLLLLAAAAAAAAAAAARGHS!
