Slang replacement for the phrase "whatcha ma call it" which itself is a slang replacement of " "what-you-may-call-it" which can be found in T. H. White's The Once and Future King.
Part of the slang vernacular of African Americans found in places such as Virginia, USA
To perform a Wichita walk off you must first catch a house fly and remove its wings without killing it. You then get in the bathtub and let your penis head float just above the surface of the water thus creating a desert island for your wingless fly to walk around on. You can also put a cocktail umbrella in your pee hole for added effect.
Whilst spending an evening in Wichita, one must wrap their wrist with their veiney peen and ask local broads what time it is. Answer is always- Time to get your dick sucked
