Macgyver guy
A Macgyver guy is someone who thinks he can do anything, even if it’s impossible. He’s called Macgyver guy because he’s like a kid who thinks he can beat up a grown man with a crayon.
He tried to fix the printer with a pencil and a curse. It didn’t work, but he still said it did.
He used a shoelace to fix my bike. It broke again the next day.
He tried to build a spaceship with a bottle cap and a swear word.
