When an attractive girl sends you all the signals that will make you think that you totally and absolutely will sleep with her that night and it never happens for no definitive reason, resulting in the condition known as blue balls.

Guy 1: Dude, I'm totally making out with this chick at the bar. I am so taking her home!
Guy 2: Awesome!
2 minutes later...
Guy 1: The chick just left! I thought she was gonna sleep with me!
Guy 2: Sorry dude, you just got smurfed!
