3.
When you accidentally fart while laughing. Often times the offender -- surprised by the flatulence -- will laugh longer than necessary and sometimes a little louder in hopes that anyone in the area will not have heard the gas.

Unfortunately, this only brings more attention to the situation.

Larters often leave the scene to not only out of embarrassment, but to hopefully drag the smell with them.
Dude, why'd you walk away so quickly?

I larted and I think Karen heard it.
