Drift
If a tsunami hits your helicopter while you are jackhammering, it will drift out to sea. What were you doing with a jackhammer at a time like this? Now your helicopter is drifting away!
Picture your helicopter as it drifts out to sea with the tsunami.
ひょう
ただよ
None
As it drifts away you shout, "Heyooo! (ひょう)." You know the helicopter probably can't hear you (or understand you) but maybe it will turn on and stop drifting away if you shout it enough.
"Heyoooo stop drifting awaaaay!!"
