Originally inspired by the legendary Ironman Triathlon held every year in Hawai'i consisting of a 2.4 mile (3.9 km) swim, 26.2 mile (42.2 km) marathon run and 112 mile (180 km) bike race. Its current usage however has come to be a reflection & demonstration of the legendary sexual prowess of the normal Hispanic male or female.

Joe: Oh shit dude, you're a total fucking Ironman!
Luis: Please save it Joe, I'm just getting started. Just wait till I really decide to break her in half!
