Secret Meat
This is interesting. The term "mystery meat" has been around a long time and its very off-putting. "Secret meat," ostensibly, means the same thing but, honestly, its a way better branding. "Secret meat" is seductive. Its alluring. It feels like it could be sexy. Whereas "mystery meat" makes me think I may get salmonella. And not erotically.
Erotic Salmonella would be a good band name, now that I think about it.
