Airstream Technical words

[Zeppelinium]

AEROWOOD has been complaining that I use too many technical words in my posts. I sympathize and empathize with him, so I propose we keep a running Wiki-Stream of descriptive words for the hard-to-describe parts of our favorite machines...

framus--important part whose function is not well understood
thingy--part with an unknown function, one that you would not be proud to have fabricated; alt: any complicated part referred to by most (but not all) females
doodad--usually left over after putting something back together, yet the something works just fine
widget--fits into things, sometimes used to hold things or space things
device--something that has an actual function, made up of several machined parts
#$@&&^ --a doodad that is either heavy and has recently landed under full gravity on some extremity or has sharp edges and has been grasped in an area where you have no visibility
jaggies--usually the edges of items in a low resolution digital image, but in this case, damaged edges on any aluminum part that will attract the attention of anyone viewing your restoration
dohickey--a device whose function is clearly obvious to the casual observer but to explain it would take several minutes

Alternative definitions welcome.
