Lunderstorm

A rainstorm in which sudden and simultaneous lightning and thunder (lunder/thightning) is a frequent occurence.

“This is like something from a movie, the whole street just flashed white, it’s a total Lunderstorm!”

Gunderstorm

A violent and uncontrollable expulsion of the bowels that results in a rancid pile of fecal matter and partially digested food.

Sometimes you have to fart after eating Taco Bell and sometimes it turns into a full blown Gunderstorm instead.

Yo, gross, it smells likes a Gunderstorm in here!
