Insanely large. Something that takes up an excessive and unneccessary amount of room. Usually silences people at first sight. Some people may feel uncomfortable being around something like this, due to their inability to divert their eyes... cuz everywhere they look, its there.
I was at a party and someone called my name. When i turned around, my humonstrous muscles knocked some chinese guy down from across the room. He tried to kung fu me, but then i just pointed at my muscles and he backed away.
