Speed of Light Fart
Speed of Light Fart:

A fart which starts to smell a few seconds before it is heard. A speed of light fart behaves much like thunder and lightning. A person capable of a speed of light fart can quickly exit a room before it is heard and thus leave the blame to another person.
The other day I was in the elevator with another person when I started to smell something terrible. A moment later and that person left and just after the door closed I heard a loud fart noise which I did not make. I then realized that the other person had speed of light farted.
