I can teach you my language
A dumb way to say you want to have sex. Usually said by someone who thinks they're hot because they're from another country.
He said, "I can teach you my language," and then tried to dance with me in the grocery store.
"I can teach you my language," he said, while trying to impress my mom.
She said, "I can teach you my language," and then tried to sing to me in a loud restaurant.
