I’m going to agree with others that this isn’t very specific to DnD, so shouldn’t be posted here.
Now if you were asking about toxic masculinity experienced at the DnD table, then it would be more appropriate.
A small, sillier one is two of my players constantly feel the need to one-up each other when it comes to height or muscles in-game. We started a new campaign and one person mentioned their character was 6ft. One of these two goes “well my character is 6’4”” and then the other (not the first) goes “well my character is 7ft”.
Like guys do we really need to do this, in DnD?
