A term used when someone having a massive erection looking as if its about to burst out of their pants. Origin of this word lies in "Chey-Town" of North Las Vegas, first seen on a morbidly obese Junior of 2009. Ever since then, people refer having a huge hard on as a "Max Wood."
Ew, dude! That kid is totally having a major Max Wood!
