Shamrock Shake

When performing a four leaf clover using the mouth, and all four dicks cum at the same time.

Cindy was getting the ol' four leaf clover and ended up with a Shamrock Shake.

Shamrock Shake

When you insert a four leaf clover into someone’s asshole and you fuck them with the four leaf clover still inside. It’s best to cum while still inside to give it that shamrock shake feel.

“You keep talking to me like that I’m finna give you a shamrock shake!”

Shamrock Shake

When a Irish bitch gives you a wet tit-job in a McDonald's (usually in the restroom but if your lucky, through the drive-through window)

Person 1: "Yo I got a Shamrock Shake at the local McDonald's bathroom."
Person 2 'Why in the bathroom?"
Person 1 "What."
Person 2 "What?"

Shamrock Shake

This is when a person dyes their pubes green and then has the partner cum on the pubs. After the cum settles the partner then consumes the solution.

“The shamrock shake I had last night was delicious!”
