BUR #25117 has been rejected.
create alias breathplay -> erotic_asphyxiation
we have autoerotic_asphyxiation, which is for choking yourself for sexual purposes.
we have asphyxiation which is for any choking, including non-sexual choking.
we also have breathplay for choking a partner sexually, which I could not find despite looking for it for a minute, because that wasn't a name I would think of.
alternatively, this could go in reverse if people would prefer that.
