The male Ph.D candidate adjuncts at my former place of employment fit that description without exception. I'd add: lifeless pale skin, unkempt hair, unmatching outfit, worn out shoes, horrendous smell of coffee-on-coffee-on-dust-on-Big Macs-on-coffee.
There is a student/instructional assistant in my PhD program who looks like a hipster, but cleaner. He is so hot.
