What does "ace [something]" mean? Also, in what circumstances could I use the word "ace?"
Answer from a Native speaker
To "ace [something]" means to do it with success! If you describe someone as "ace," it means they're very good at what they do. It's also the name of a card in a deck of cards. Lastly, these days it's used to describe someone's sexual orientation when they have little to no sexual attraction to others. So it depends on the context that you use it! Ex: We need an ace to win the card game. Ex: He's an ace in the kitchen. => he cooks very well Ex: I'm pretty sure I aced my audition! => I did very well in it. Ex: She identifies as ace.
