Shamrock/Clover neck tattoo

It indicates being popular in the prison or gay community. That guys can get "lucky". Particularly when placed just below the ear, it is a marker for how far down they like to deep throat and that they swallow. It is also known to be used as a target by the sissy of the group who would kneel in the middle of a disturbingly aggressive homosexual circle jerk.

That guy is advertising that he is a cum dumpster in the prison and gay community with that shamrock/clover neck tattoo.

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!”
