MacGuaff - Something so big it could make a giant cry and a dwarf proud

Something so big it could make a giant cry and a dwarf proud.

That MacGuaff of a coffee cup could hold a whole lake and still have room for a whale.

My MacGuaff of a suitcase was so big, it had a door and a doorman.

I saw a MacGuaff of a dog, and it had a gym membership and a side of bacon.
