A combination word used to describe something which is extremely large. Larger than life. Derived from "gargantous" and "gigantic."
"Someone told me that Lou Ferrigno was smaller than Arnie; like he was only five foot four or something! WRONGO! I saw him at a downtown nightclub! They practically had to take the door off the hinges so he could get in. He's gargantic!!"
