A black man with a British accent.
I might be able to provide one of the criteria you mention. Back in the year 2000, when me & my girlfriend left the UK for a while & went to Grosse Pointe, MI, to a home she had there, she invited a friend around. I’d never seen this friend of her’s before.
I had not long come out of the shower, and I went into the room where they were. (I was dressed I hasten to add). I introduced myself to her & she shouted,
“OH MY GOD, SAY SOMETHING ELSE!” I find it a bit difficult speaking on demand to someone I’ve never met before. I smiled and said to her,
“What do you want me to say?”. She said,
“ANYTHING!”
The accent thing works the other way around too.
Later in the evening when she was leaving, she was at the front door with my gf. I heard her whisper,
“does he sound like that in bed?”. My gf very quickly turned her around & pushed her out of the door and into the cold winter night. There was 12 inches of snow on the ground.
