Goops are disgusting creatures with bad manners, featured in a poem called Table Manners by Frank Gelett Burgess. It is from the book Goops and How to Be Them, published in 1900.
Gelett Burgess also wrote The Purple Cow. He was a professor at Berkeley, wrote several books of humorous poetry and mystery stories; he illustrated his own books. He was fond of making up words; his creations include blurb, goof, and bromide.
The Goops they lick their fingers,
And the Goops they lick their knives;
They spill their broth on the tablecloth --
Oh, they lead disgusting lives!
The Goops they talk while eating,
And loud and fast they chew;
And that is why I'm glad that I
Am not a Goop -- Are you?
The Goops are gluttonous and rude,
They gug and gumble with their food;
They throw their crumbs upon the floor,
And at dessert they tease for more.
They will not eat their soup and bread
but like to gobble sweets, instead,
And this is why I oft decline,
When I am asked to stay and dine!"
