Snaptism 

Derived from the word 'baptism', a snaptism is the day in which any given Snapchat user joins Snapchat. It's to be treated like a digital birthday of sorts.

Zack: Twelve months ago on this day, I created my Snapchat account. Therefore, today is my snaptism

Jack: Happy snaptism!

A Slaptism is when you get Jewish'd by a Shalomander

Yo you're about to get Jewish'd by that Shalomander
