Definition of "Tongue bite"?

[Emjaysmash]

So I read this in a recent article from pipesmagazine.com on Burely tobacco (HERE)

" Of all the different types of tobaccos, the one most likely to cause bite is Burley, but it’s important to understand that tongue bite is a biochemical reaction, not the same as "leather tongue" which is what one might get from smoking too much or too hot.
When tongue bite attacks, it feels almost like a cramp. Because the reaction is caused by the high pH of the smoke, having something to drink that us somewhat acidic, like a dry wine or even soda can help fend off the discomfort."

For a while I had thought I had known what Tongue bite was, and actually experienced it. Now (at least from this definition) I would categorize all my tongue bite incidents as "leather tongue". This is mostly due to the fact that I found that drinking soda or alcohol would increase the pain of my tongue, and the pain was intermittent (not constant from smoking the pipe).

Do you agree with this definition? Have you a better one?
