A large mountain of crap that sticks out of the water in the toilet bowl, much like an island in the ocean. This is often the result of drinking Guinness to the point of passing out the prior evening.
I just dropped the biggest Ireland's Eye. That bathroom is going to stink for days!

Get the Ireland's Eye mug.
Nessan the Duke of 400 AD had three sons, and named a monastery in their honor. the monastery is on the island called Ireland's Eye. The name of the island is 'Inis Mac Neasain' or the 'Island of the sons of Nessan', the monastery has the same name in Gaelic.

The monastery is good craic for a quick visit during the summer. Not a huge amount there today but an interesting place all the same.
Dave: Did you go to Howth and see Ireland's Eye?

Kevin: Yeah it was good fun, I enjoyed the Island of Ireland's Eye
