Why does Deadpool love Chimichangas?

I just want to know about the backstory and details referring to this obsession

Because I guess that is what 13 year olds think is funny.

It isn't just chimichangas. He also likes pancakes and tacos.

However.. sometimes he does go a little overboard..

Because who doesn't?

He actually doesn't, he just likes saying the word.

"This place makes the best chimichanga on the island. Don't even like chimichangas all that much. I just love saying it. Chimichanga. Chimichanga. Chimichanga. Chimichanga." - Deadpool, Cable & Deadpool Issue #13

Chimichanga!!

because everyone has a favourite food

It reminds him of a simpler time before...

(Cries)

The cancer

He doesn't, he just likes the word.

Cause he's so lolrandom, and it's a funny sounding word.

Because he sucks.

It was a inside joke from one of the writers.
