Wait, so if this saying is a "mind your own business" type of thing - it would only come up in certain circumstances, for the most part, right?
Like, I post my cook kit in a thread and you say
"You can do it better like this."
and I say
"Hike your own hike, m8."
But if you're posting your gear or your plans then you must be doing one of two things.
*Submitting them for criticism and advice, so you can improve.
*Showing off.
If it's the former you wouldn't be saying "hike your own hike," right?
>omg you're supposed to be impressed at how much money i spent on this sweet gear, not telling me i can go lighter for less money!
