Please, I would really be grateful if you can tell me what the sentence is saying:
Stardom radiates from him like a New York billboard as he lights up the stage and side swaps his audience with his unique comedic humor.
particulally, the problem is with ...and side swaps his audience with his unique comedic humor. Not really a clue.
side-swap - to hit something from the side. "I side-swapped that wasp that was about to land on my plate".
In the context of the sentence, the person's comic act has a final meaning that is not obvious until he gets to the end.
