Zac Efron Grabbing His Bulge on Set Will Leave You in a Cold Sweat

It's official: 2015 is the year of appreciating Zac Efron's nearly naked body. The actor has worked on three movies so far this year, and he's been shirtless — if not in his underwear — in all of them. Zac's most recent adventure found him on the set of Neighbors 2 in Atlanta, just this week. He wore tiny orange shorts and proceeded to twerk, flex his muscles, and grab his bulge in front of a huge crowd. Before that, he was all wet and rippling in Hawaii while filming Mike and Dave Need Wedding Dates, and back in April, he overwhelmed us while wearing nude underwear on the set of Dirty Grandpa. Clearly, Zac's girlfriend, Sami Miró, is one lucky girl. Keep reading for what might be our favorite pictures of him ever.
