1. When a person, who is deceptively strong for the amount of muscle that they have, can lift the same amount of weight or more than someone who is a lot larger.

2. When a skinny kid comes out of nowhere and is insanely strong... and no one knows...
Jim: "I was at the gym today maxing out at 280 lbs..."
Andrew: "That's awesome!"
Jim: "But then this guy who looks like he weighed half as much as me did that weight as his warm up. He freakin muscle juked me."
