When someone is so fucked up, they head in one direction with a goal in mind but half-way there, forget that goal and wander off in a random direction with or without another goal in mind. Term comes from goldfish in an aquarium acting the same way due to their seconds-long memory.
He was so fucked up on mushrooms, he spent the whole night goldfishing around his apartment and never made it out to meet us.

We wasted a few hours goldfishing around camp before we even realized that we missed the burn.

The purest little animals that swim around in large cuboids filled with water. When it comes to goldfish, opinions are rather polarising - there are really only two types of people: those who have an undying love and experience monomania towards those creatures, and those who openly dislike them as think that they're boring little lumps that open and close their mouths.

Far too often, they are portrayed in unfunny Youtube videos as memeable and clumsy things who only exist for the human race to laugh at.

its time to stop.
Far too often, goldfish are treated as though they're nothing more than entities that exist for us to laugh at.

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."

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 "

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!
