A shuffle pattern is simply a triplet pattern (3 notes per beat) with the middle triplet omitted.
So if your triplet pattern is counted:
1-trip-let, 2-trip-let, 3-trip-let, 4-trip-let (repeat ad naseaum)
your shuffle would be:
1- -let, 2- -let, 3- -let, 4- -let,
This creates a sort of syncopated feel. Blues & country songs use them a lot. It's a fun pattern to learn and use. I've only broken the surface with shuffles on the guitar, but I love them on the drums.
(can't believe I forgot) "The Animal" on Passion & Warfare
Led Zep's "Fool In The Rain" is a half-time shuffle.
"Hot For Teacher" uses a super-fast shuffle pattern on the double bass drums.
Plus, (I think, see below)
"Tobacco Road" is one, too.
"Juice" on Alien Love Secrets
I know I'm forgetting a huge number of examles. The problem with naming examples is that it's easy to confuse the jazz triplet pattern with the shuffle, especially if they're fast or indistinct. I'd have to listen to be sure on lots of the ones that are coming to mind.
A number of songs with have the jazz triplet pattern with a shuffle bass pattern. This only confuses stuff even more.
