Arrangement under which a chick gives a guy an open option to hookup with her on a given night, say Fridays, if he contacts her by an agreed time, after which she is free to do anything else she wants.
Lindsay to her friend Tasha: "Brian has first call on me Fridays until midnight. If I don't hear from him, we'll go bar hopping and see what's going on."

(Sucks to be the chick btw).
