What's the difference between HoHo's and Ding Dong's

Well, once for enjoying a practical joke, and the second time around for having a jester who will do anything for the object at which a sexual euphemism of a “ding dong” usually is directed.

Enjoying a practical joke is “gay”?

What, you don’t think enjoying a joke is happy and lighthearted?

This is errie.

Both Ho Ho and Ding Dong are the nicknames of somebody I know.

Yes. If you use this definition: “Showing or characterized by cheerfulness and lighthearted excitement; merry.”

How about Ring Dings and Ding Dongs? Same thing, different companies? Or a regional thing?

“Ring Dings are better than anything!..etc.”

I’ve never seen a Ring Ding here in the Pacific Northwest

Ding Dongs = Big Wheels = Ring Dings.

Anything is better than Sno-Balls, though. Bleh.
