A deep fried hot dog is called a ripper.
The reason that deep fried hot dogs are called a ripper is because when the deep fried hot dogs ends and casings start to rip apart when they cook in the oil.
So if you want to order a deep fried hot dog you can ask for a ripper hot dog.
However some people may not know that the deep fried hot dog is called a ripper and may not know what you're talking about.
If that is the case just call it a deep fried hot dog.
I've ordered deep fried hot dogs in hot dog buns and topped with nacho cheese and it's a great way to eat a hot dog.
If you've never tried a deep fried hot dog with nacho cheese you should as it's really delicious as nacho cheese goes well with just about anything other than nachos.
