M'vertibrae - When you drop like a sack of bricks and instead of swearing

When you drop like a sack of bricks and instead of swearing you just yell ah m'vertibrae like it's some kind of magic spell

I tripped over my own dumb foot and said ah m'vertibrae like I was a wizard

He face-planted the floor and just said ah m'vertibrae like he was trying to summon a pizza

She dropped from the stairs and said ah m'vertibrae like it was the best line in the history of ever
