Warning: Scat talk ahead...
If you do the dirtiest of deeds at work, here are some terms you may find helpful:
CROP DUSTING: When farting, you walk really fast around the office so the smell is not in your area and everyone else gets a whiff but doesn't know where it came from. Be careful when you do this. Do not stop until the full fart has been expelled. Walk an extra 30 feet to make sure the smell has left your pants.
