From his video podcast, Free Speech. His Millennial's rant starts at 45:30 and that continues into his advice for young men.

A few quotes:

"From 17 to — for dudes I'm going to say 30 — just fuck everything."

"Hangover 2 shouldn't be your life story, but you need that under your belt, especially in your party years."

"Fuck 8's if you can — you should definitely be seen with 8's — but my experience has been you don't beat off about them in later years, you beat off about the 5's and the 6's because you can do anything to them..."
