Four Leaf Clover 

When two girls press their naked breasts together and a guy titty-fucks the center.

Guy #1: So did you get lucky with that girl last night?
Guy #2: Sure did. Turns out she has a kinky roommate with big tits. Let's just say together they helped me find a Four Leaf Clover!

Four Leaf Blowver 

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!

This year's Four Leaf Blowver was amazing! Our cocks were green, our semen was white, and Carrie's hair was orange; her head looked like the Irish Flag.

Four Leaf Clover 

The art of inserting the thumb of four different guys into the anus of another person, male or female. A special handshake is created to allow for the insertion of all four thumbs, which resembles a four leaf clover from a top view.

This dude was acting up, so we gave him the ole Four Leaf Clover.

four leaf clover 

when a woman has four penises (or dildos) inserted into any one of her orifices making the shape of a 4 leaf clover. Note: this requires the use of a small and very tight hole so that there is tension against the penises (or dildos) or the hole will tend to be shaped more like a square (commonly referred to as "square dancing" with a female)

Her asshole was so tight that it took us a long time to get all 4 cocks inside her, but when we did we were rewarded by the beautiful tight pucker of her four leaf clover.

Four leaf clovers 

Small, insignificant weeds that some superstitious people beleive are made by small green fairies, who dance and sing in an Irish accent and love gold in pots under rainbows. Therefore, these unitellegent people find this weed lucky, and they go on long idiotic hunts to find one. Most people are utterly disapointed when they come up emptyhanded, because most people can;t find four leafed clovers.

Gee look: Four leaf clovers! Just like in the lucky charms cereal! Wow!
