On St. Patrick's Day four guys cover their erections in green frosting and place them on a fifth party's face, the "Four Leaf Blowver" is the process in which the fifth party member sucks the frosting off each erection. When all the frosting is sucked off of the erections the "Four Leaf Blowver" is complete.
Person A: Who do you think performed a better Four Leaf Blowver last St. Patrick's Day, Dave or Stephanie?
Person B: I hate to say it but I think it was Dave who performed the better Four Leaf Blowver!
