It’s honestly such a pity when the joke can’t be translated I’m so sorry about this
WELL LIZA IS THE BEST AND SHE TRIED TO EXPLAIN THE JOKE FOR YOU:
“Ok, so, even this is kind of impossible I’m TRYING to translate this for you, non-Spanish speakers.
First, this joke is OLD AS BALLS.
When you change all the vocals for an e in “Mi moto alpina derrapante” you get
“Me mete el pene de repente” (more or less “He suddenly puts his dick in me”). And. Well. It’s funny because dicks?”
Honestly “mi moto alpina derrapante” means nothing it’s just to make the joke it translates for something like “my alpine skidding motorcycle”?? I DON’T KNOW.
