Universal greeting
From MediaWiki

The universal greeting in the Generation 1 universe, introduced in Transformers: The Movie, is commonly transliterated as baa wheep graa na wheep nini bohng.
It is used as a means to express good will toward alien beings when a language barrier is present. However, it does not always work that way. The Alligatorcons on Quintessa reacted violently to the greeting, chanting it as they attacked Hot Rod and Kup. However, the Junkions on the Planet of Junk took it rather well and threw a party.
(Note: In the Japanese version, the Universal Greeting is pronounded "Berwip crawna-wi pinibon".)
