Being vers is hard enough, and finding people who are fully vers and not leaning one way or the other, a pain in the neck. This would be SO EASILY SOLVED through a flip-fuck tag... If it existed it would be the only tag I use. And explaining takes an ungodly amount of characters in the profile. In Spanish it's "Vuelta y Vuelta". I don't know in other languages. But it would make my grindr experience so much easier.
