There’s an expression in the geek community, “ha ha, only serious,” that tells the listener that the previous parody, joke, etc., may have been intended to be humorous, but also includes a large degree of truth.
This comes up because I was explaining to a friend a large part of why “Like a D6” (that I mentioned earlier in Parody) was funny. For a lot of gaming geeks, hanging out around a table playing D&D, wargames, boardgames, etc., is just as fun and looked forward to just as much as a “good time” (if not more so) as hanging out in a club with friends and dancing, etc.
