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.
