XKCD 2501 comic -a conversation between two people - only it reads:
1: "Bonk Wave is second nature to us Fedi Artists, so it's easy to forget that the average person probably only knows socool and sknob."
2: "And AxWax, of course"
1: "Of course."
[Even when they’re trying to compensate for it, experts in anything wildly overestimate the average person’s familiarity with their field.]
