Flaccato is an Abbreviation of "Flying Staccato" - a musical term used mainly for stringed instruments. The bow repeatedly hits the string in the same place of the bow. This is done by the hand and fingers of the right arm making little clockwise circles, thereby requiring the bow to "stand" in the same place.
Example: Flying staccato (Flaccato) Mendelssohn Concerto, 3rd movement, measures 137-144.
