Sentence:  [T]he release of semen from the penis predominantly symbolizes a forceful masculine operation, an orgasmic ‘rush' – ejaculate refers to a sudden happening, an ejection – while the ‘loss' of blood during menstruation is viewed as a more or less passive occurrence. Even the metaphors employed to depict these two aspects of corporeality serve to situate them on differently gendered poles. Man ‘<WSD>spoofs</WSD> off' or ‘shoots his load', while woman ‘gets her visitor', ‘has got her monthly'. 
Meaning of the word marked with <WSD> tags:  To ejaculate, to come.
