A lady (often quite large,) that prefers the (very) close company of other ladies, known as femmes. Regularly seen wearing a lumberjack shirt, boots and dungarees/bib & braces overalls.
Origin: Due to the normal extreme mass of these 'ladies,' it has often been assumed that locomotion could only be facilitated with the assistance of a powerful Diesel engine.
