Developing a theory of the Skinny Rat Boy archetype in which there is a precise length of too-long stringy hair that shifts the character from piteous but maybe hot?? to Villainy
Mitch from Dazed and Confused: shoulder length hair, innocent
Ziggy Sobotka from The Wire season 2: mostly in "overdue for a haircut" territory, more pitiful than villain but still kinda sucks
That guy in the Arkangel episode of Black Mirror: basically bottom of the neck, absolutely a predator
Further research is needed
Do you have any idea how hard it is to search for "skinny guy in movie whose hair is a little too long and usually is maybe a drug dealer or a stalker but also maybe likes poetry and is sensitive???"
@ingrid waifish guy who serves as emasculated foil to male lead yeah
dylan moran did that in "shaun of the dead"
@ingrid keiran culkin in "scott pilgrim vs the world?"
@ingrid mathew lillard, hackers (1995)
@ingrid not to massively reply here but (a) i have been nerd sniped and (b) actually ziggy falls into the "emasculated foil for the rugged men" trope with the dock workers
@ingrid "we can't get Jeremy Davis, who have you got?"
@ingrid so everything Steve Buscemi has ever done?

Is this actually a thing or did I just make up a kind of guy
