John Stamos isn't a real grandpa, but come September 29, when "Grandfathered" premieres on FOX, he will be playing one on television.
And if you have certain feelings about that, John Stamos wants you to know: It's okay.
In an interview on "Jimmy Kimmel Live," Stamos readily acknowledged that he's a very particular kind of grandfather.
A grandfather best described by a particular kind of acronym.
A grandfather you'd like to... well. You know. YOU KNOW.
Check out the video below to see Stamos inaugurating the term "GILF" into widespread use on national television. Don't bother googling it; you'll just be automatically redirected to the actor's Wikipedia page (okay, not really, but it's only a matter of time.)
