Rooooooooo! 

The sound Sylvester Stallone emits from his mouth when diving away, avoiding, or jumping from a fatal explosion; or if Stallone is absent: a Stallone type character, actor (most likely Arnold Schwarzenegger), or animal (most likely a dog)

(Some guy) Look out!
(Stallone) What?
*Looks at ticking time bomb just about to hit one second.*
(Stallone) Rooooooooo!
*Dives away from explosion.*
