One man's romantic dilemma is putting a movie behind schedule in this short comedy. Cocky Jason (Peter Karinen) and jittery Skip (Brian Sacca) are two actors working on an independent crime drama with cryptic German director Barry (James M. Connor). While Jason is trying to make his way through the big scene that will he's certain will win him the Independent Spirit Award, Skip keeps flubbing his lines, much to his co-star's annoyance. Finally, Skip confesses to Jason that his mind is elsewhere and he needs some advice; the night before, he was lucky enough to spend the night with Abby (Casey Wilson), the boom operator whose shapely behind is the talk of the set, but he's not certain if what happened between them was really sex. Screened at the 2007 South by Southwest Film Festival, The Definition of Sex was written by actors and comedians Peter Karinen and Brian Sacca, drawn from material created as part of the duo's improv act.
