padacillar - What you say when you're so out of it you think 'caterpillar

What you say when you're so out of it you think 'caterpillar' is 'padacillar' and you yell it like you're the worst person ever.

I saw a bug and yelled 'padacillar' like I was cursed.

I tried to say 'caterpillar' and it came out 'padacillar' like I was brain-dead.

I said 'padacillar' like I was the worst human being on Earth.
