The jizz from masturbation that a Hipster wipes off his stomach because he has decided that intercourse is no longer 'in'. Translation: He masturbates because he can't get a date, because he doesn't know how to talk to the opposite sex, because he is a FUCKING HIPSTER.
A: So, how was it?
B: Yeah, I wasn't really into her, anyway.
A: But you were talking to her for a while, I thought.
A: So, you thought your negativity would just eat away at her sense of self worth to the point where she would consider you attractive?
B: That's how it usually works.
A: Hm. Well, what now? Hipsterjism?
B: Where's my sock?
