A thing that’s so big it thinks it’s a superhero and you’re just the sidekick.

That MacGuaff of a pizza was so big, it had its own theme song and a fan club.

My MacGuaff of a backpack was so big, it had a fridge and a couch inside.

I saw a MacGuaff of a sandwich, and it was so big, it had a side of drama.
