INCH kit = I'm Not Coming Home kit
Is this a new term? havent seen it before

The term can feed unexpected thoughts in the wrong mind. What if you have a non-prep wife and she thinks INCH means You are running away with another girl. The kit would contain a dozen condoms and wetwipes to remove lickstick. Oh, and a lengthy list of wife-proof execuses

LOL
Seriously though. If the term BOB is there, why the need for more terminology ? People of average IQ like me barely can sort out all the existing ones.
Back to the original (prep conflict).
I think if you want to store a complete system ( BOB, or INCH ), we can only store them with someone we trust completely. However with partial kits, PHRASECENSOREDPOSTERSHOULDKNOWBETTER.-grade kits , city-boy-junk kit , lazy-boy-convenience kit ..etc. you should be able to easily find a place to store/hide them wherever you live or work.
