Get the grimus mug.
A derogatory term for Afro-Americans. As the use of the word "nigger" has become less frequently used by the masses, the term "grimus" was coined to "hold the black man down".

This term was first used as a deroatory statement when a black man moved to Florida from the Chicago land area and began to turn color from exposure to the sun. When found to turn from chocolate to black to purple a friend of said black man called him "grimus", changing the landscape of racial epithet's forever.

The plural form of "grimus" is "grimus".
"Grimus keeps coming up to me on the train and asking for money!"

"Grimus please!"

"Grimus loves him some collared greens, fried chicken and grape drink."
