Get the Fart Biscuit mug.
The most annoying of all farts. It is not as deadly and destructive as the dread cheese, egg or dog farts. However, the drop biscuit fart lingers a lot longer than the aforementioned farts. It's as if this fart is baking in the over just flicking you in the nose with its' annoying odor. You may or may not see a pale brown cloud emanate from the farter's ass after a drop biscuit fart.
Christ almighty, that goddamned Benson, he started off the road trip by launching a drop biscuit fart in the jeep and put the power lock on the windows. That friggin' fart rode the whole 2 hour trip upstate with us!
