What Up is a phrase commonly used by Barney Stinson, usually heard at the end of a comically appropriate sexual comment, often accompanied by a high five. Its style varies from time to time as do most of Barney's catchphrases, being either high-pitched or low-pitched, oddly pronounced or even not verbally said.

When whatever is being referred to is doing something it is not supposed to be doing or taking a form it is not usually in. Mostley used in dark humor.
