A phrase started by the infamous public access TV show host Alexyss K Tylor.
Vagina Power means to not let the pussy be offguard and let any penis go all up in your vagina. Vagina Power and Penis Power are always constantly in battle, but if women stand strong in Vagina Power the will win.
Stand in Vagina Power and manifest your destiny!
That girl has no Vagina Power, she lettin people play her outta her pussy!
