She is one of those aggressive, demanding, in control females. Many men with low self esteem are intimidated by her.
She's the scientist who researches the merging of ovum, or long term sperm preservation or those lesbian frogs in Texas. You might catch her in the school room asking for a big strong girl to open the windows. She is that tidy housewife who tells her daughter "math is fun" or "run along dear, and play on the computer". She is everywhere. Fear her.
