Urban Dictionary on Broscience, this one made me laugh..

Jock: "Dude, your body only absorbs 20 grams of protein at a time and you can't train a body part more than once a week."

Informed response: "That's broscience, bro. Your stomach and liver can handle a large sirloin with more than 20 grams of protein just fine. and if you think you can train a body part only once a week, then why do you masturbate every day?"
