When a guy shows up at a bar or club like he's on a mission and hits on every girl in the place. If one girl gives him the cold shoulder, he forgets her instantly and goes to the next girl, who might be the one who just gave him the cold shoulder or her best friend.
At the bar, Dan hit on Rachel, got ignored, and then started talking to Rachel's best friend, who was still with her ex.
Mark tried to flirt with every girl at the club, even the ones who were in the middle of a fight.
Steve got turned down by Emma and immediately went to her best friend, who was also Emma's ex.
