Just as I was taking photos of my work my daughter breezed in, picked up the earrings and said: "Mum, these are really awesome!" I had to confirm her reaction by looking up current definitions and here are a couple of options I found:
- Impressive and frightening. So impressive or overwhelming as to inspire a strong feeling of admiration or fear.
- Extremely good. Informal extremely good. This word is used mainly by young people.
