A Splergio is a man who is so good at sex that he can make a girl cum within 1 minute of sex. She will splurg all over the place, and the man will lay down satisfied, covered in bodily fluid, knowing that he is a Splergio.
Lina: Did you have sex with John the other night?
Sara: If you could call it that! I only lasted 40 seconds, he's such a Splergio.
