Blue toast is having the monger use mouthwash before getting intimate. I never heard of blue shower though. Could be another way of saying the same thing? Weird.

Yup. And if you scroll through enough search results, you'll see it there as well; not just on profiles. In the same header spot, you'll see other names like secret playdates, LVC assistant, Posh booking assistant, Dreamgirlsaz, and so on.
