The very thing that is offensive about farting. It's the reason you can smell a fart, because it's actually tiny little pieces of poo floating around, ready to land on you. Or your food.
Person 1: Hey, who farted?
Person 2: Dammit!! I had my sandwich out, now it's covered in poo particles!
On a molecular level, whenever someone chucks a fart
you are inhaling their poo particles
I had a curry last night, poo particles were flying everywhere
Particles of feaces that float around in the air directly after a particularly greasy fart.
That stinks! I can taste the poo particles already!
Pronunciation: 'POOO PAHHH-TA-CLES"
Airborne particles that are 'sprayed' into the air due to the flush of a toilet, causing the air to become polluted with people's 'poop particles'.
Ex. "She left her apple on the sink in the Ladies' room; now it's covered in customer poo particles".
