Marcus Campbell, creator of PaddyNotPatty.com and its associated social sites, corrects the frequently misspelled shorthand for St. Patrick's Day as well as some other Irish stereotypes.

“Paddy is derived from the Irish, Pádraig, hence those mysterious, emerald double-Ds," writes Campbell on his site.

"Patty is the diminutive of Patricia, or a burger, and just not something you call a fella. There's not a sinner in Ireland that would call a Patrick, ‘Patty.'”

Still curious about which shortened version of St. Patrick you should go with?

It's Paddy, not Patty. Ever.

Saint Patrick's Day? Grand.

Paddy's Day? Sure, dead-on.

St. Pat's? Aye, if ye must.

St. Patty? No, ye goat!

For Campbell, opting for ‘Patty’ is purely "Daft."

Campbell also makes clear that shamrocks have only three leaves, Irish Car Bomb drinks and cupcakes are still considered controversial, and in certain contexts, the term ‘Paddy’ can be read as an ethnic slur.
