Melch 

A melch is someone who tells jokes, sometimes said jokes are dirty. It is derived from my name(chelsea) and menstrual-enstrual-anian. I have no idea what that means, but it is part of melch. I also think it could mean someone who talks too much.

You are such a melch.
Stop being such a melch and shut up.

Melch 

To defecate on the ground and proceed to stomp on your own feces barefoot until your feet are thoroughly covered in it. Your partner will then suck on your feet and toes until their mouth is full of your feces and you will then kiss them exchanging your feces mouth to mouth.

Man, I love to melch, It just tastes so good and I love how intimate it is.

Mechatronics 

A mistake.
A program that lures innocent high school kids who want to make cool robots. Half the class end up becoming web developers.

"So... you transferred from ECE to Mechatronics?"
"It was a mistake."
