The Lunge.

A ballestra is a rapid attack in fencing made by a jump forward and a lunge.

The correct spelling of the word is "lunging." It refers to the action of thrusting forward, as in a lunge exercise or a fencing move.

if you're talking about the move you do (extending your arm and thrusting forward) to hit your opponent and score a point, then it is mainly called a lunge, although the part where you thrust forward could be called a "thrust". <<nooo, reeeally?
