At the end of sentences in casual form I know you can use ～じゃない or ～じゃん to say "~isn't it?" similar to ～ね. And I know ～よ at the end of a sentence can be used like "I tell you" or for emphasis, but what happens when you use ～じゃんよ at the end of a sentence, like in the titles of Space Dandy episodes (the examples below)? The official English episode titles all end with ", baby" so I feel like it's a speech pattern of someone who considers themself kinda cool. E.g.
Live with the Flow, Baby
The Search for the Phantom Space Ramen, Baby
Occasionally Even the Deceiver Is Deceived, Baby
