An evolved greeting deriving from a strange not-quite-meow of a kitten. Since first being introduced, "Merp" is now an acceptable word to use as much as possible, to confuse non-merpers and to connect with the crazy cat community, and is slowly being used more often in everyday life.

Can also be used as an adverb (Merpy), a noun (e.g. silly Merp!) or verb (She was Merping)
