Top Definition
The term used for an element that can do anything and everything you might want it to do. I.E. you need to build a bridge under a volcano, Lavamantium is the way to go. It is mostly used to argue any and all points against people that think they know about science and chemistry. Its an irrefutable argument because it can never be wrong, Lavamantium is always right.
"That thing was clearly Lavamantium, nothing else can survive being shot by Optimus Prime."

"Well everyone knows that Titanium is the strongest metal for construction"
"I think your forgetting Lavamantium, you can build bridges inside Volcano's with that shit."
