gritch /grich/   1. n. A complaint (often caused by a glitch).
2. vi. To complain. Often verb-doubled: “Gritch gritch”.  3. A
synonym for glitch (as verb or noun).  Interestingly, this word
seems to have a separate history from glitch, with which it is
often confused. Back in the early 1960s, when ‘glitch’ was
strictly a hardware-tech's term of art, the Burton House dorm at
M.I.T. maintained a “Gritch Book”, a blank volume, into which
the residents hand-wrote complaints, suggestions, and
witticisms. Previous years' volumes of this tradition were
maintained, dating back to antiquity. The word “gritch” was
described as a portmanteau of “gripe” and “bitch”. Thus, sense 3
above is at least historically incorrect.
