A word used to describe a certain person who exhibits large amounts of strength, particularly when using the arms. (i.e. screwing a bolt tight on a motorcycle, then breaking it due to sheer force.)It is derived from the American name, Maurice (Mo) and Gorilla (rilla).Can also be used as an verb, see examples.
"Why in God's name do you need an airgun to take off a front wheel? You let Morilla tighten the pinch bolts again, didn't you."

"You really Morilla'ed that bolt into place!"
