have a blast
Meaning
To have a great time; enjoy yourself a lot.
Origin
Originally, “blast” refers to an explosion or strong burst (of sound/air). By the mid-20th century in American English, it broadened informally to mean an exciting, high-energy experience—hence “have a blast” = have lots of fun.
Notes
Casual, upbeat phrase for parties, trips, events. Not used for serious contexts; it implies energetic, memorable fun.
