Rogue Peanut

(noun) A peanut that varies in size. It is usually brown in color. Despite it's slight color variation, it is nearly indistinguishable from other peanuts. The only purpose of the rogue peanut is to make an awful taste in your mouth when eaten. A taste of bitterness and sourness and shame all combined into one.

A bought a bag of bulk peanuts and more than half of them were rogue...so i threw them all out. Rogue peanuts ruin everything.
