Mistaking a male Thai prostitute for a female one can be called a 'trick of the thai' due to how ladylike many of them look. It's usually an excuse made by men who were out shopping for some ladyboy action, got caught getting it and then didn't want to admit to it after. Because why would they not just check up front if they didn't want it? It's not like we don't know that they're out there. Lurking.
"Whoa, hey Stan, this girls got balls!"

"Wha...err...oh, no way. Total trick of the thai man, I well thought it was a girl. Honest."

"Hmm."

"Yeah...can I have five minutes to finish off?"
