Someone with an extremely short memory, or one who is extremely absentminded.

Derives from the evolutionary defense mechanism of the American Goldfish in order to stave off insanity due to boredom: "wow look at that pretty plastic tree"... "wow look at that pretty plastic tree"... "wow look at that pretty plastic tree"
"Damn...That Sue never learns... She just does the same dumb shit over and over again like a goldfish."

Someone with a memory of 7 seconds or less, as defined by the legendary Monty Python.
Goldfish 1: Hey, look at that castle!
Goldfish 2: What's a castle?
Goldfish 1: I don't know, why d'you ask?
Goldfish 2: Ask what?
Goldfish 1: Hey, look at that castle!

Great crackers from Peppridge farms. They're baked, not fried, come in different varieties, and smile back. Try mixing them up all in one bag.
Hmm... pretzel, pizza, cheddar, and color goldfish mixed in one bag.

1. A popular pet often kept in bowls (which they shouldn't, that's bad for them) and often thought of as having a 3 second memory, though this is a myth, because in reality goldfish have a longer memory than you do.

2. The snack that smiles back.

3. People that have a super short memory, originating from the myth that goldfish have a 3 second memory (which they don't)
1:

SMART son:"Mom, I found a goldfish!"
Mom: "Ok, keep it in your bowl"
SMART son: "FUCK YOU YOU DON'T KNOW SHIT ABOUT TAKING CARE OF GOLDFISH"

2:

"I had some goldfish yesterday. I wonder why it was smiling at me even though it was gonna die and get digested and turn into shit."

3:

SMART daughter: "Dad, look at that goldfish!"
Dad: "Oh, that's a person, not a goldfish!"
SMART daughter: "DUMBASS I WAS THINKING OF THE PERSON "
