Hella Irish 

A slang term from San Francisco, used by teenagers meaning: To get EXTREMELY drunk. You are not getting truly "Hella Irish" unless you are drinking a 40 in a North-face jacket. When people say "Hella Irish" they often do the Shaka hand sign, except they make it seem as if they are drinking from a bottle. These teenage boys often get "Hella Irish" at a magical place called "The Grove"

Jack: What happening this weekend?
Danny: We were all going to the grove, Hella Irish!
Jack: I'm so it! Lets get HELLA IRISH!!!

Irish Hello

An Irish Hello is when you sneak into a party and hide for twenty minutes before walking out as if you’ve been there the whole time.

Jack pulled an Irish Hello last night. We didn’t even see him show up. I just looked behind me and there he was mingling with everyone.

Irish Hello

Similar to an Irish Goodbye, an Irish Hello is a hen you wait until you are absolutely sure a person is leaving before you make an effort to acknowledge their presence. It’s a dick move but everyone does it so get over yourself.

“Roger is finally leaving. Let’s go over and give him the ol’ ‘Irish Hello’ so he doesn’t think we’re dicks and invites us back to his sick beach house next summer. Man, I hate that guy.”

The Irish Hello 

The Irish Hello is a newly coined term derived from the already famous phrase "The Irish Goodbye". Essentially, it is the opposite of the "Irish Goodbye". The perpetrator of the "Irish Hello" will hold court, and show up to a place, party, event, or meeting, uninvited, and unwanted without any foreseeable indication of their arrival. Its first origins date back to John Paul Occhipinti's famous exile and return to his home in Scranton, PA. John Paul Occhipinti left his son John Salvatore Occhipinti the reins of the home with permission to throw countless, and endless parties, only to return from Ocala, Florida with no notice, intentionally killing the buzz of the summer parties that were set to ensue.

John Salvatore Occhipinti was in the midst of a Blockbuster House Party only to receive "The Irish Hello" from his father, John Paul Occhipinti who was in a Mesh Beach T-Shirt waiting at the door. John Salvatore had to leave his Beer Pong Championship Match to help unload his father's luggage, knowing full and well this Irish Hello was the Irish Goodbye to raging hard as fuck.
