I had dubbed it as 'overacting effect'

where even a teeny bit of a sensation gets an explicit reaction appropriate or not.
It's just as 'automatic' as one would 'let it' permit with the opposite (under reaction), as opposed to manual on either 'directions'.
Didn't knew what it was really called, really. Had yet to search what it is...
Had done 'both' myself, on accounts of my own discovery and other else's remarks or their reactions.
That's a much better way to put it than "I'm such a spaz," which is usually how I feel about myself.
