Jumbai is a positive recognition which originates from the english word "yes". Jumbai is also the primary word spoken in the tribal language which was spoken by the Sasugon tribe in North-Western California.

More recently, Jumbai can be heard being used by people with mental disabilities who are trying to describe an emotional event.
Modern day English:

Q: "Will you be accompanying my to the circus this afternoon?"

A: "Jumbai"

Sasugon language:

"Jumba Jum Jum Jumbai! Jumbai Jumbai Jum!"

That translated into english would mean:

"There's a large chance I will rape you in the next 60 seconds, unless you start making out with me immediately"
