If you meant to type "whillie" but it turned out to be a misspelling, there are a few possible correct suggestions. Maybe you meant "while", referring to a period of time. Alternatively, it could be "whistle", a high-pitched sound produced by blowing air through pursed lips. Lastly, you might have intended to write "wheelie", a maneuver where a vehicle's front wheel is lifted off the ground while accelerating.
