Because of the need for equality and acknowledging women (or other people) who have vaginas as powerful of sexual beings as
men (or other people) who have penises, the counterpart to big dick energy is big vag
juju. Big vag energy would immediately indicate a large sized
vagina and that does not sound as appealing. Playing on the female menstrual cup, "JuJu Cup," and the French word "juju" meaning talisman or lucky charm, "big vag juju" was born noting that "big juju" is attributed to the amazingness of the
vagina, not necessarily its size.
"Where have you been all of
my life, lighting up this room like a giant LED sent down by the
aliens by radiating all of that big vag
juju around here?"
