Stands for "Too Much Hipster". You often see this guy walking around downtown, going to the most underground, coolest places, wearing too tight t-shirts, most often decked out entirely in American Apparel, sports the super cool nerd glasses, may be a bit unshaven. Basically too cool for school. Similar to the hipster douche
, this guy is like a superpowered, hipster to the extreme from head to toe.
"Yeah, he reads Nylon and listens to electronic funk pop, he's a film student and he is in a band."
"Wow, that guy is TMH."
