Cambridge shamrock 

When, on St. Patrick's day (or night), a guy living or staying in Cambridge blows his load on his girl, preferably her face, while simultaneously flinging a handful of bright green glitter at her so it sticks to the jizz.

Yeah, we fucked for a bit, but when she asked me to turn off the Dropkick Murphys playing in the background I had to give her a Cambridge shamrock.

V. To shit in a cardboard box then proceed to mailing it to someone. This can be done for either revenge or for beneficial reasons. If you plan on doing more than one at a time drinking prune juice is advised.

Guy 1: Man, my math teacher gave me an F in her class.

Guy 2: You should Chris Shamrock her, bro.

Guy 1: Good Idea! Got any prune juice?

Jizz Shamrock 

When you blow your load on your chick and mix it with green food coloring in the spirit of St. Patrick's Day

I woke up this morning to my boyfriend giving me Jizz Shamrock face painting. Complete with green food coloring and sprinkles.
