The Brief: The dashing away emoji represents wind, air, or a cartoon-like dust cloud.

DEEP DIVE
This emoji is perfect for situations that involve gusty winds, smoking, or speed. Flatulence is another scenario where this cartoon symbol could be used. A word-based translation would be “air” or “dust.”
Smoke until I canβt no more I guess π¨π¨π¨
