A luimarco is a self proclaimed natty bodybuilder who relies on two testies, on a daily, baby please to make sub par gains in the gym. They are typically 40 year old virgins who even though claim to have 2 working testicles they never actually get the chance to use them. They use annoying catch phrases such as: "two testies, baby please!", "bubble gut bonanza", and "anabolic chicken." They also like to rip down others who have a far superior physique than they do. They are an annoying creature.
