Blast

Back in ancient times - like the '60's - 70's many people would have a lot of fun and a great time. When they would talk about to others they would say they "Had a blast!" They had a fantastic time.

"I LOVE my new car! Drove it to California and back! Had a blast!"
"Went out dancing with the girls. Out late! Had a blast!"
"Today we rafted down the river. Several rapids! Whoohoo! Had a blast!!!"
