A cross between a creepy man and a hipster. He usually tries to get into your pants while crying about how original he is. Creepsters always have a sparse mustache or thick beard, and have dreams about being a rockstar. A creepster might try to hide his adoration toward Edward Cullen with many anti-Twilight posters that host sexy pictues of Robert Pattinson. Hipster girls are inexplicably attracted to him, if only ironically.

Ellen: "He rubbed his beard on my face while he read 'The Catcher in the Rye.'"
