Originally used as a derogatory nickname for Ypsilanti, Michigan. During World War II large numbers of people moved from Kentucky to Ypsilanti to work in the bomber factories. The town still has many residents who trace their roots to the Appalatian Mountain states. Also spelled Ypsitucky. This once pejorative nickname has been proudly embraced by some residents, similarly to the way the once derogatory moniker 'queer' has been embraced of late by homasucktuals.
That son-bitch is a stupid, racist, redneck, hillbilly, white trash, asshole from Ypsi-tucky.
