jabberchanic
An Automotive Mechanic that will go on in great detail all the makes and models of cars he/she has worked on and/or repaired but will have no photo evidence nor written example of doing said repair work. Often works out of a shop one would not take any kind of equipment with an engine to let alone their valued automobile. Usually has saggy pants or coveralls soiled with so much grease/grime there is no hope in Hell of ever coming clean no matter how much bleach you use. Loves to talk about the Super Cars that they have "wrenched on" regardless of the fact the shop in which they work is no where near the "value" of said Super Car.
I dropped my car off and the job that takes 2 hours took 4 because the Jabberchanic had to tell me about all the Fancy cars he has worked on over the past 6 years.
