Like the poet said

A phrase used to jokily articulate or emphasize something you said, which was most definitely not said, ever, by a poet.

Friends talking:
Friend 1: "yeah dude, it's gonna be fkn LIT, like the poet said
Friend 2: "what poet said that?"
Friend 1: "common dude, it's a saying"
Both of them then burst out in joyful laughter
