What is "E" speak

I recall reading about it once but all I recall is it is English except you don’ use any for of the verb “TO BE.” Is this right?

If so why? What is the advantage?

The language is called E-Prime, and its main advantage is that you don’t ascribe traits to objects absolutely. For example, you would say “Jake acts like an asshole.” instead of saying “Jake is an asshole.”
