Dom Mazzetti is the satirical persona created by Mike Tornabene, the star of the viral YouTube channel Bro Science Life. Since his debut in the early 2010s, Dom has become the face of gym culture satire, blending hyper-masculine tropes with absurd pseudo-science about lifting weights. The character is known for his signature tank tops, sunglasses, and the iconic gunshot sound effects used to punctuate his points. In the meme world, Dom Mazzetti is used to represent the bro perspective on fitness, dating, and lifestyle choices, often mocking the overly serious nature of professional bodybuilding or the sheer ridiculousness of casual gym-goers. It’s the go-to template for anything related to leg day, protein shakes, or general gainz logic.
