Such things shouldn’t be allowed anywhere on GS! For those who bear allegiance to Islam, this is an abhorrent activity (and a grusome sin, come one! at least admit that this would be zina) , too abhorrent to even joke about (which is clearly not the case as the poster was being serious)
as for those not pertaining to Islam, well most decent folks would call this suggestion vulgar, unless they have a different set of standards to define it.
