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

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.
