Just randomly came across the 'otoko_no_ko' tag as a replacement for the 'trap' tag and when following related tags I had found 'reverse_trap' to still be a tag. When I thought about for egalitarian purposes why not make the suggested tag with 'reverse_trap' aliased to 'dansou_no_reiji'.
It's not a big thing but something to think about. Of course this may take time to get a rewrite for that wiki but I think it'd be a nice touch to have both genders having a bit less troublesome implications for the concept.
