Mercat

An animal whose sole evolutionary purpose is to express displeasure at a situation/person. "Mer" is both the Mercat's mating call and a signal it is about to attack.

"Mer," said Felix the feral Mercat, upon finding out his favorite stripper was out sick and was therefore unable to give him his customary Wednesday night lap-dance, "Mer mer mer."

Walter Mercado

Someone who can sense the possibilities of others, but who may be unable to see the dangers in his own life because he is a dreamer. Walters are charismatic, kind and sensitive people, who should be cherished whenever you find them. Many are artists or spiritual people, wonderful to be around, and some are even quite fabulous.

John is a Walter Mercado, be nice to him because he won't always be around.

mercaptoethanol 

(1) A substance used typically to reduce disulfide bonds between cysteine residues in proteins.

(2) The most disgusting odor producing substance known to man. It will make you yearn for the smell of urine after a plate of asparagus.

"Mary mother of God, did a rat die in the wall?" "No, I'm just prepping my PAGE samples and I'm using mercaptoethanol."
