Friction will cause heat and enough heat will cause a fire. Imagine fire starting using a spinning piece of wood, but done try it it takes forever to create enough heat. Burning (friction burn) has become the term used to describe excessive wear on strings. Twisting, smashing, and sawing could just as easily be used to describe the results from poor stringing methods.

TWISTING - Have you ever noticed the top / bottom few crosses appear to be twisted more than any other strings in the racket? Let's assume you are stringing a racket and a cross grommet hole is covered by a tensioned main string. If it is a snug enoug fit and there is any texture at all on the string, like the twist of a multifilament, when you pull the string through the string will twist on the outside of the frame (and twists the opposite way on the inside if you are pulling the string through the crosses) and causes kinking. To avoid that pre-weave the cross before tensioning the main. When you get down to the bottom it is a little more difficult but way to avoid twisting. Also when a main is very close to the grommet it tends to twist the string inside the frame and even if you fan the strings as you go the string still runs over/under that main and can cause notching so be careful. Using the fins built into grommet or scrap string can help here.

SMASHING - Clamps can cause a lot of damage to string if not adjusted and well maintained. The opposite here is a clamp not tight enough. If the string slips any in the clamp it really eats the string up. Crushing strings by having the clamps too tight weakens the strings too and could cause premature breakage.

SAWING - A real good example of the sawing action can be seen when pulling poly crosses over a soft main. Fist time I stung Xcel main with hurricane crosses I could see right off it was going to be a problem. The poly will saw into the soft tension main very fast especially on the outside mains. Be very careful with this combination. Tis sawing action is probably what you're referring to when you mentioned burning. Weaving one ahead helps, but many people to to speed up the process by not pulling through that one string and leave the tip only pulled through so they don't have to look for the end. That method only increases friction when pulling the cross through.
Everyone has the right to be stupid... it's just that some people abuse the privilege
