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.

A common occurrence at rock and hardcore shows where an audience member will attempt to mouth along to the song being played but having no idea what the words are. They will often simply open and close their lips in a manner similar to a goldfish.

When a man masturbates, ejaculates skyward, and then attempts to catch his own airborne gob of semen in his mouth. This act is known as goldfishing for the manner in which a goldfish patiently awaits his feeding while swimming vertically, mouth ajar. Men who goldfish tend to be unpleasant, lonely, and simple human beings.

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.
