Gnoxmas

I attended an unusual event on June 27th, known as Gnoxmas. I googled it and discovered that
"Gnoxmas (n): Event held every year in Ireland on June 27th, to spread gnosis. The traditional meal at Gnoxmas contains gnocchi.

Gnox (n): 1. Followers of Gnoxmas 2. Slang term for gnosis."

I think it's a Gaelic word, but I'm not sure.
