I thought about fixing that, but it seemed like a yak shave…
Good gravy, I did nothing last week but shave yaks!
"What are you up to?"
nods gravely in pained agreement
What the hell are these people taking about? Let's clear it up.
A Yak Shave (or Yak Shaving) is the end of a chain of incremental causal dependencies. Imagine the situation where you need to do a, but first you need to move b out of the way, and then you can’t move b because of c being broken, so you go to fix c, but that needs tool d, and tool d is only sold at store e, and store e is run by a person you promised to do f for, and before you know it you’re busy doing x, y and z, where z is breaking into the local zoo, and y is shaving a yak, because x needs yak hair to complete.
