Rabbi Orlofsky likes to use colorful language and expressions. I don’t think he believes all men are pigs, however he was speaking about young teenage boys who are looking for gf. Those boys tend to be in it for one thing and one thing only.
It is also true that any adult male can be a pig. Hashem created men with a very powerful drive. If it is not guarded and reigned in, a man can easily becomes a pig and addicted to his desires.
