A car, usually an old American car (1930's-1970's) who seems determined to skin, slice, and slash the hands of every mechanic who touches it, regardless of their skill-level. Resistant to tools, penetrating oils, vice grips, and laws of physics. Any bolt that is in this car will STAY in this car, whether you want it there or not, and if you try to remove it, it WILL break off, and leave you requiring 15 stitches in the process.

Like when your taking off a rusty U-clamp bolt from a muffler with a ratchet and you apply full force and the bolt snaps off forcing your hand full force into a jagged rusty piece of metal on the frame or some shit.
