Loser vs Looser
A loser is well, a loser, a word we use to insult someone usually when we feel upset. Just like what this person did when they called the other party a loser after a heated disagreement. Except they didn’t spell it just like that, they typed in ‘looser’, which is when something is loose, like a loose nail or knot.
The other person decided that the first time they spelled the word was the correct way and reconfirmed what they had written. This would then completely backfire in their face when a screenshot was posted with the definition of the word they were using and a further insult provided. Talk about a double burn.
