Gallimasaurus
The fatty, grumpy, human meatball who hangs out with the girl you want to get laid with. Especially when they ruin your vibe with their dumb jokes.
Her Gallimasaurus told a joke so bad it made the whole row laugh and then cry.
I was about to make a move, but her Gallimasaurus just snorted soda all over my shirt.
That Gallimasaurus is like a cheeseburger with no bread, messy and useless.
