This is is terrible it's not funny.
People need to stop for a moment at these things and think of the consequences (and what caused it).
This only perpetuates the stereotypes and the objectification of people.
It also promotes the hidden hate that people have for the opposite sex, the unspoken one, that is given by this false knowledge (men thinking women are just annoying walking holes, and women thinking men are a bunch of brainless penises).
By doing this, people will also be less inclined to trust in others and open themselves, and will be more inclined of being content with the first person they find that seems to pay the minimal attention that maybe only an object would deserve, at least in romantic relationships.
In terms of friendship, this only contributes in making people more and more superficial in judgement.
These things have consequences, and you should study them people.
Because we live in this society all together.
