Well I'm 40 and lived all over the country and I've never heard it a single time. You sure you don't live in an alternate timeline? Also just to make sure I'm not crazy I looked at iHop's online menu and it's... just pancakes. Never heard anyone call a pancake anything other than a pancake.
Ah, yeah you're thinking of regular pancakes. In this thread, we're talking about crepes made in one of the Scandinavian styles. I haven't heard of IHOP selling those unless it's a special menu item.
Edit: I googled IHOP Swedish pancakes and they apparently had them for awhile and discontinued them a couple years ago.
