Janky turd is a term commonly used in BMX bike circles to describe a shitty BMX bike. The term was started on the BMX Museum.
That new Quadangle bike is such a janky turd! two of the four bolt holes in stem are threaded at an angle, bearings in bb are notchy, cranks are bent, chain looks like it was spray painted in driveway by my 8 year old nephew, freewheel and hub failed before i reached end of street. Fuckin janky turd!
