Noo

Something that is worse than no, but not worse than nooo.
In other words, a middle level, even tho it can be infinite, like
Nooooooooooooooooooooo. That would be the the definition for losing an eye, cracking a rib, having a heart attack, and then the world exploding after a giant meteor hits.

You: I dropped your phone in the river.

Victim: nooooooo
Or
You: I took a dump and clogged up your toilet and then made your dog eat it, witch ended up in him vomiting all over you white carpet.
Victim: NOOOOOOOOOOOOOOOOOOO!!
