The act of avoiding a salutation despite eye contact with someone you have met/been introduced to/have kissed/had sex with. Particularly prevalent in Galway, Ireland, where people actively and awkwardly don't acknowledge each other. Galway Hello; it's a non-thing.
That guy that I've met and talked to like ten times just gave me a Galway Hello. What a douchebag.
