No. Never on accident. 

I have on accident.

How do you say a curse word on accident, anyway?

Well, it just sneaks out! Like when you're not thinking, and your gut takes over.

Usually, when my gut takes over, I start saying them, mean every one of them, and I didn't do it on accident. Y'know, me and you are two totally different creatures.

That's probably why I just don't understand you sometimes.

Thank you to @iluvrainclouds for the ask!
