what's "rolled on a hat"

That kind of hat...Duh  thanks

You know when you take a Hostess Ho Ho or a Little Debbie Swiss Roll up and you unroll it?

And then you wrap it around your pee pee so she can eat it off?  That's also called "rolling on the hat"...  or "I'll eat your hat"  or "Ho Ho Hat"  or "Debbie's Bonnet" or...

I'm sorry.  Forgive me.  I'll stop.  My blood sugar is low.
