Contrary to the Irish goodbye, an Irish hello is the act of promising others you will attend an event/party and then never showing up nor cancelling last minute.
Ryan committed an Irish hello when he RSVP'd to his friend's wife's birthday party , but decided he didn't want to go and never showed up or let anyone know, and looked like a total asshole.

telling a group of people you want to call it a night - then after you convince the group leave the baryou circle the block and go right back in the same bar
What you do last night?? I was with an awful group of people last night. I pulled an irish hello and then was out until the bar closed
