Server Pussy
The 23-27 yr old women who work as waitresses and bartenders that every 40 something, newly divorced man tries to screw at the local bar he hangs out at because he has no real social skills or friends. He tries to hook up with them because 1) he thinks he looks cool if a girl 20 years younger then him is interested in him (his money) 2) He is CONVINCED that he is hot and wants to prove it to the world and 3) she is the only women he sees on a frequent basis, because he is always at the same bar night after night. Eventually, she dumps him for a man younger then him and this man dies alone and wishes he had dated a woman his own age.
"That creepy old guy at the end of the bar is always here. He's trying to get himself some server pussy."

"Hey, is that (______)'s daughter?" "No, its the server pussy he's been trying to tap since his divorce."
