Better. ;) However, while that indeed eliminates excessive backtracking
as \S or \w results in (since they contain the underscore), this doesn't
match "words ending in underscores". A non-underscore [^_] includes
space, punctuation, and any other unwanted char.
Exactly _five_ occurrences of an '_' underscore, with up to 30 _random_
chars in between. This paragraph matches. :)
Sorry. I lost sight of that part...
/(?:[^_\s]{1,30}_+){5}/
