1. An exclamation from a friend who yells at another to hurry up or get moving. This is referenced usually when one is taking an inordinate amount of time and a member of a group or gang is late for an event, such as smoking a bowl with others, getting stupid and/or dumb at the sideshow or nightclub, stealing a car or TV, or catching that last bus or BART train.
"Yo nigga we late for the sideshow, get ya ass up and hurr rup."
Adjective (used with object) 1. The act of thinking, being, or behaving as one would if they were a Derr Herr. 2. To emit or come up with new words to describe a new situation or person.
Origin of Derr Herr: Thought to have originated in Middle English to describe a Herder (one who herds cattle or sheep), more recently found to have come directly out of Haven-ology. Haven-ology is a new form of language that uses syllables with vowels and consonants to create new words to describe a before unknown situation or person. Haven-ologists (one speaks or understands Haven-ology) are few, and most are considered to be a Derr Herr themselves.
