I don't really know about gagle, but gaggle means:
'Gagle' is not an Irish word. 'Gaeilge' is the name of the language in Irish.
A Gagle Spot is said to be a huge purple "wart" on the tip of your nose. It usually itches and the more you itch it, it grows larger and larger until it explodes.Even though this skin problem is fictional, a Gagle Spot is embarrassing and gross. If you Just happen to have one, put wart medicine on it. This could sting, and extremely bad to swallow.
