Just because you put on deodorant in the morning, you're not 100% safe from B.O. After a workout or just lazing around in the sun, you can accumulate a disgusting amount of sweat. So don't trust your pits; if you really want to measure your stink, sniff your balls.
But you can't actually get your nose down there (we're guessing), so you've gotta smear a sample on your hand. "Your balls will tell you everything," Jordan Carlos explains in this clip from Tuesday night's new "Guy Code." And if your balls tell you to take a damn shower, then do it ASAP, because Melanie Iglesias speaks on behalf of all women when she says, "If a guy has stinky balls, I know what I won't do."
