learn you a lesson

i'm sorry, i don't usually pick faults with grammar as grammar rules can sometimes be too picky but i'm afraid the phrase is 'teach you a lesson' not 'learn you a lesson'. that's why a teacher teaches, and a pupil learn.

teach you a lesson is usually used as a threat indicating impending violence.

jimmy: yo mama is so ugly, she turns people's stomachs!

phil: you son of a bitch! i'm going to teach you a lesson!

(this phrase should be teach you a lesson and not learn you a lesson.)

learn you a lesson

Also related to the absurd patriarchal plea for control. "You must learn lessons, this is why I'm teaching you." Infamously responsible for closing the spiritually liberating "third eye." The phrase, "learn you a lesson," seems to be an unconscious, funny way amongst friends to remind one another how much it sucks to be taught by force. It's amazing how the mind never lets us forget until we forgive.

"That'll learn you a lesson!"
