Someone who thinks Irish culture is the best thing since sliced bread. They'll probably start a fight if you say 'French fries' instead of 'chips.'
I dated a paddyphile once. She tried to convince me that 'Irish coffee' was a love language.
He wore a shamrock on his head to work. No one asked why.
I got into a huge argument over whether 'Irish stew' is a real thing or just a myth.
