Nickname of the Icelandic volcano responsible for spewing massive ash clouds during an eruption in April 2010 grounding multiple flights over Europe. Eyjafjallajoekull, the real name of the volcano, is nearly unpronounceable by people who don't speak the Icelandic language.
The airlines are saying to disgruntled stranded customers, "The Ash Hole is an act of God. It's not like anyone can stop a volcano. Except maybe Al Gore."
Ummmmm.... Ay-jah-fah-yall-a-joe-coo? Whatever. The Ash Hole.
