One thing outshines another
Mogging means outshining or outperforming someone or something, making the other seem less impressive by comparison. Collins labels it slang: a casual word for being thoroughly upstaged.
Imagine bringing a cupcake to a party. Someone else arrives with a three-tier cake covered in berries and flowers. You might joke, ‘My cupcake just got mogged.’ Both could taste lovely. The joke is about how dramatic the comparison looks.
Mog, mogged and mogging
Dictionary.com’s slang guide describes mog as a verb that can refer to appearance or performance. You might see mogged for something that has already happened, or mogging for the action.
Here is another invented example: ‘Your paper aeroplane mogged mine.’ Perhaps yours sailed across the room while mine dropped beside the chair. The speaker is admitting they were outperformed, with a little exaggeration.
The word has a backstory
Collins traces the slang to AMOG, short for ‘alpha male of the group’, but qualifies that origin as ‘said to be’. Dictionary.com links its early use to online communities focused on male dominance and status.
The word later spread into broader, often joking comparisons. That history still matters: a joke about two cakes can land differently from a comment ranking people’s bodies. The surrounding sentence and who it targets help you judge the tone.
Tracing a word’s history is called etymology. It can explain where an expression came from without fixing how everyone must use it today.
A dictionary’s choice
Collins chose mogging as its Word of the Year for 2026, highlighting its playful and ironic use. That is Collins’ selection, rather than a single award shared by every dictionary.
When you meet the word, ask what is being compared. If one thing is being presented as spectacularly outshining another, you have the meaning. The cupcake can still be delicious.
