padacillar - When you’re so tired you can’t even say 'caterpillar' and yo

When you’re so tired you can’t even say 'caterpillar' and you just say 'padacillar' like a dumbass who got hit by a bus.

I fell asleep on the couch and yelled 'padacillar' like I was haunted.

I heard a noise and screamed 'padacillar' like I had no brain.

I tried to say 'caterpillar' and it came out 'padacillar' like I was a retard.
