Dragons Bell 

When your scrotum shrivels up, and looks like a dragons bell. The shaft is the neck. Tip is the head.

Dude it's so cold out. Friend "yeah I have a dragons bell."

Dragon Belly 

When someone doesn't appear to have a strong core but it's actually rock solid.

"Hey, Drew's been going to the gym a lot hasn't he?"
"Yeah ... He doesn't look different though."
"Eh, maybe, but he's got a Dragon Belly now."
