Dick is abundant and of low value
Dick is abundant and low value is a phrase that is widely used by women to put down men and is thus a form of casual misandry. It is intended to convey the idea that men demonstrate greater willingness to have sex with women than the reverse. The phrase was popularised by feminist writer Alana Massey in her article The Dickonomics of Tinder.[1]
Biologists have long argued that men show a greater willingness for casual sex as historically this activity has carried far higher risks for women than for men.
The statement itself is true and, in a way, the main reason for the existence of gynocentrism: those who produce the rarer (and thus more valuable) type of gametes (eggs, produced by females) are the individuals that need extra protection in order to make the group survive - and those who don't produce them (namely, males) need to compensate for that by achieving other things.
