What I have concluded from this thread by the way, is that no one has any clue what it means and there isnt a general consensus on what it means even amongst like-minded individuals.

Fascinating really .

I feel like "easily rattled / offended" is probably the closest to being accurate. Which confuses me, since as far as I can tell, it's a term that people only resort to using when they are rattled or offended
