Gobermental is correct. "Johnny Kush" is the mixed race mentally ill burnout host of the "Marijuana Happy Hour" podcast. He's been a (very) minor side character in the "Who Are These Podcasts" universe where he is covered for repeatedly (and unsuccessfully) picking fights with/begging for attention from various Dabbleverse nobodies.
If my recall of the lore is correct, he was involuntarily committed sometime in the last year or two, and has been ranting lately about his many imagined sexual escapades due to a fictitious sex addiction.
He knows nothing about Imholte or Nick aside from what he's read online, and is just making shit up because it's a topic that gets him attention. He may end up being a future lolcow topic in his own right, but can safely be ignored on any Rackets related issues.
Examples of his high quality thoughts can be found here:
