estrogen bubble
A place of employment which employs mostly women, or managed by women. It is sometimes characterized by the phenomenon that when many women work closely to one another their periods occurring simultaneously.
By the end of the month all the women at work will be synched up. There will be chocolate on every desk next to the used up Kleenex boxes. The men should run for their lives! Man, that's what I get for taking a job in an estrogen bubble.
