What you know “hooray” is in german? It’s HURRA!
HURRA! HURRA!
Although I still like the standard “hooray”, cuz it sounds more silly. HURRA is more of a gut sound, making it sound more serious.
HURRA!
Germans are serious speakers! HURRA is a fist pump in the air. Hooray is a silly hi-five.
It’s even better if you draw it out to sound like “HOOORAH!” instead of just “HER-AH!”
