A Dungeons & Dragons riddle is:
 
Q: How do you ask out a D&D player?
A: Ask them for a D8 (date).

   
The joke has been cited in print since at least 2016 and has been printed on several images.
   
     
Wikipedia: Dungeons & Dragons
Dungeons & Dragons (commonly abbreviated as D&D or DnD) is a fantasy tabletop role-playing game (RPG) originally designed by Gary Gygax and Dave Arneson. It was first published in 1974 by Tactical Studies Rules, Inc. (TSR).  The game has been published by Wizards of the Coast (now a subsidiary of Hasbro) since 1997. It was derived from miniature wargames, with a variation of the 1971 game Chainmail serving as the initial rule system. D&D’s publication is commonly recognized as the beginning of modern role-playing games and the role-playing game industry.
