A fart so concentrated and large in magnitude that it explodes through your pants and Fus-Ro-Dah's any object within 200 feet, leaving a dangerous amount of fart radiation on the area for years which gives people asskemia.
1. Did you hear that Josh let out a Mushroom Fart on his date last night?
2. In 1945, two obese Americans Mushroom Farted in Hiroshima and Nagasaki and gave many Japanese people asskemia.
A heated fart is the action of farting directly into a wall mounted electric heater turned up to maximum temperature. The fan in the heater will accelerate the dispersal of the fart. If done properly you should be able to clear out a room. This also has the added benefit of burning off the dust clinging to the electric heating elements in the summer, adding a burning dust fragrance and fire prevention.
"Why are you bent over in front of the heaterJohnson!......... and why does it smell like hot Garbage?!"
"Oh just launching my post dinner heated fart"
