The term has meant different things over the decades, from an insult towards the 60's founders to Phish Phans who were literally "dirty"and needed a shower. I see it different now.
What I see is someone who is the opposite of "
real". Instead growing up and facing themselves with love and acceptance, , they hide behind their ability to manipulate, use, and/or imitate the "
hippie"
based culture and use it as and excuse to avoid responsibility and accountability on near every level., This character is really just a
mooch in a hemp wearing, dreadlock flailing
shell. They inevitably wear out their stay everywhere or get discovered for their inconsistency to be honest, true, genuine or self-contolled. Our
society makes lots of these now, and while the shell persona may be diffenerent, the issues are still the same. Lack f accountability, and ownership of theri lives leaves them stagnant until they change,
"He was on my
couch for 2 months, didn't help out at all, bummed the whole
time and then somehow I was and asshole when I caught him stealing some stuff from my
wife. No more Dirty Hippies!"
