The normal definition of the word blast refers to a big explosion and it’s a phrase that we could often see or hear in the news for example Two men have been seriously injured and taken to hospital from a suspected bomb blast. But if you use this among your friends, it’s a lot more positive and means that something is great or you had an amazing and fun time.

Example 1)

“How was the Jack Johnson concert?”

“It was awesome. Everyone had a blast.”

“Even John?”

“Yeah even John. He was even dancing!”

“Wow, it must’ve been good!”

Example 2)

“Thanks for inviting me to your party last night, I had a blast.”

“Thanks for coming and I’m glad you enjoyed it.”
