Get the Reh mug.
Pronounced: Reh. An interjection used to commonly express anguish or aggravation, however it can also be used as a noun, a verb, or even an adjective. The word derives from "Rehhhh", most commonly known for being a raptor call. Reh must always be capitalized, for it is the focal point of any sentence.
Example 1 "Hey bro, whats up?" "Reeeeehhhh" "Oh I gotcha, that happened to me last week too"

Example 2 (commonly used for naming someone, you take the first letter of their name and put Reh on the end of it, this is the only case in which it can be a lower case Reh) Kristen + Reh = Kreh, or Kreh Kreh if you're cool.

Example 3 (basically whatever the fuck you want it to be)
