A big ken
When a guy is as big as a mountain and looks like he could crush you with one hand. He's the type of guy who walks into a room and everyone knows he's the boss.
My uncle is a big ken, he's 6'5" and he once picked up a couch with one hand.
That guy at the gym is a big ken. He lifts weights like they're made of feathers.
The big ken at the party was so huge, he took up half the dance floor.
