The phenomenon by which females become exponentially "girlier" when they congregate in larger and larger groups. This is thought to be caused by the increased availability of estrogen, the "
female" hormone, within a given radius. Some hypothesize that ovaries
serve a role in communicating with each other under such circumstances. It should be noted that Estrogen Amplification also occurs in
post-menopausal women.
The
loud, uncontrolled giggling in the
office next to me is the tell-tale sign that 5 or more females are in the same room - surely, estrogen amplification has occurred.
