I was once involved in a business enterprise with a man who wasn't a native speaker
I had talked to a child about buying some of our stuff, and he was psyched about it and went off to fetch a parent to complete the transaction
I was talking with my colleague about it in the interim, and said of the kid "he was sold" as a way of summarizing his receptiveness to my pitch about our products
My colleague became very alarmed. What do you mean, sold? Who bought him? What do you mean?
This can happen with new players who are native English speakers too, as D&D has a fair deal of vocabulary not everyone knows. Words like charisma and melee really got popularized by D&D.
Deep cut here: When I was a kid (ages past) and first heard friends talk about D&D, I thought there was a lens to keep you on the border. And without it, you might go straight Into The Unknown.
Im pretty sure I saw this as a visual gag in a Muppet Babies comic book in the 80s! I think it was issue #13… I might still have it packed away somewhere
