A really big character in the book Gulliver's Travels. They are 60+ foot tall humans, and everything in their land is 10x bigger than things in the regular person world. It makes a guy jealous to think that these Brobdingnagians have 80 inch long penises, and boobs 60 inches across, etc.
Brobdingnagians are the only beings with bigger penises than I have.

To be endowed, as to be 3 legged, as to play putt-putt without renting a putter, as to be the Dylan to the Dangler, as to a Battleship in a puddle.
It looks more brobdingnagian with the lights on, due to his personal brobdingnagian he custom orders pants.
