What is the name of Kotlin! operator

Question

When I talk with other developers, what do I call an operator !!?

In Kotlin ?:is called the operator of Elvis

These sources do not say the name !!:

• http://kotlinlang.org/docs/reference/null-safety.html#the--operator
• http://kotlinlang.org/docs/reference/keyword-reference.html

If you look online, then the general term for !!is a double hit . Do I use the same for Kotlin, even if the swift operator !is called force deployment (Note: !in swift it is similar to Kotlin !!.)

What I am specifically looking for:

• A name I can orally call an operation !!that Kotlin developers can understand
• A name other than a double exclamation mark or bang bang or double bang

Kotlin in Action calls this a non-empty statement statement. We decided to update the documents to use this term too.
