Insulting term usually directed towards a male describing them as the epitimal "girly wuss bag". This word made its worlwide debut in the classic stoner's hit movie "Harold and Kumar go to White Castle," where Kumar, striving for greatness, doesn't just resort to calling Harold a girl; he christens Harold a Vaginamcginastien. More than a little bitch, feebler than the vag, this is the rock bottom of absolute bitchdom a male can fall to.
