"Ass Completo Gigante" - Insult or Edible? .

Today in the way of news, while riding/clinging to dear life on a squirrely-Santiago bus, I saw a billboard advertising:

"Ass Completo Gigante"

Now here's what I know -

The "completo" is a Chilean fast-food mostrosity, consisting of:

a hotdog as long as your forearm

on giant hoagie roll
w/ serious gobs of mayonaise

ketchup

mustard

hot pepper sauce

avocado

onion

tomato

the Chilean kitchen sink

But this "ass completo gigante," I can't be too sure about.

Possible translations:

1) If you eat this hotdog, you will have a gigantic butt forevermore.

2) While you eat this hotdog, you will look like a complete, gigantic butthead.

3) This gigantic hotdog is made completely of animal butts.

Alls I know is, I am not looking to try an "ass completo gigante" anytime soon.

I am simply reporting. Just the facts, ma'am, just the facts.
