buffet

1. (countable) A blow or cuff with or as if with the hand, or by any other solid object or the wind.Examples: "On his cheek a buffet fell."; "October 30, 1795, Edmund Burke, letter to Lord Auckland those planks of tough and hardy oak that used for years to brave the buffets of the Bay of Biscay"; "Kipper stood blinking, as I had sometimes seen him do at the boxing tourneys in which he indulged when in receipt of a shrewd buffet on some tender spot like the tip of the nose."Synonyms: blow, collision, cuffcountable

2. (aviation, uncountable) The vibration of an aircraft when flying in or approaching a stall, caused by separation of airflow from the aircraft's wings.Examples: "The aircraft configuration was such that there was little or no warning of the stall onset. The inboard slats were extended, and therefore, the flow separation from the stall would be limited to the outboard segment of the left wing and would not be felt by the left horizontal stabilizer. There would be little or no buffet. The DFDR also indicated that there was some turbulence, which could have masked any aerodynamic buffeting. Since the roll to the left began at V₂ + 6 and since the pilots were aware that V₂ was well above the aircraft's stall speed, they probably did not suspect that the roll to the left indicated a stall. In fact, the roll probably confused them, especially since the stickshaker had not activated."uncountable
