"I'm going to be giving you the tutorial to the perfect crotch grab," the "Jealous" singer confidently tells the camera in the funny clip.
"Now, it's very simple," he says, before going on to explain: "You need three things: a hand, a crotch, and a willingness to do anything. So my basic steps are turn to the side, profile is better, make sure your hand is ready and just go for it. That's it, that's all you need."
The singer's shirtless photo shoot with Flaunt last month wasn't the first time we've seen Olivia Culpo's boyfriend take it off.
In 2013, the Camp Rock alum shared a surprise shirtless selfie on his Instagram. A less bold Jonas captioned the pic at the time: "I never do this but... Healthy living and fitness update. Post workout picture. #diabeticinshape #2.0."
