Ladino
A form of Spanish that Sephardic Jews used to speak before they got kicked out of Spain. It's like Spanish with a little Jewish attitude and a lot of profanity.
My brother said, 'I can't understand a word my grandma says,' and I told him, 'That's because she's speaking Ladino.'
My teacher said, 'Ladino is like Spanish with a little bit of Jewish swear words.'
My cousin’s dog barks in Ladino and it’s terrifying.
