Interesting, spanish has variations of “son of a bitch” “son of a whore” “son of a slut” and other more ‘original’ like “son of a twig climber”, that last one “twig/stick climber” is another euphenism for slut in spanish (trepa palos) the euphenism aludes to the slut clinging onto the man’s dick.
The Mexicans I grew up with were all obsessed with penis pictures in grade school. Would flash them but always pinkies.
