A (), Iberian slap, forearm jerk, Italian salute, or Kozakiewicz's gesture, is an obscene gesture that communicates moderate to extreme contempt, and is roughly equivalent in meaning to "fuck you" having the same meaning as giving the finger. To make the gesture, an arm is bent in an L-shape, with the fist pointing upwards; the other hand then grips or slaps the biceps of the bent arm as it is emphatically raised to a vertical position.
It is most common in the Romance-speaking world (Spain, Italy, France, Portugal, Romania, Belgium, Latin America, and Québec), Russia, Poland, Hungary, Bulgaria, Croatia, Serbia, Turkey, Georgia, Ireland, Tunisia, Algeria and in parts of Scotland.

International nomenclature
In Italy, the gesture is often referred to as , meaning literally 'umbrella gesture'. Its most famous occurrence in Italian cinema is in Federico Fellini's (1953), where the idler played by Alberto Sordi jeers at a group of workmen, combining this gesture with a raspberry. In Brazil, the gesture is known as a "banana" and carries the same connotation as giving someone the middle finger. It can also be used to denote disrespectfully ignoring what someone just said, analogous in meaning to the expression, "I don't give a fuck". In Japan, the gesture has a positive connotation, often used to convey courage or determination. To perform the gesture, a hand is placed on the opposite biceps, and then the biceps is flexed, as if the flexed biceps were being polished. Sometimes, the gesture appears in video games produced in the country; as a result, it often has to be removed during the process of game localisation to avoid causing offence. Portugal has the term , a diminutive of 'sleeve'. It is also the most characteristic gesture performed by the Portuguese everyman Zé Povinho. In Poland, the gesture is known as or ('Kozakiewicz's gesture') after Władysław Kozakiewicz, who famously displayed this gesture after breaking the world record and winning the gold medal in the pole vault at the 1980 Summer Olympics in front of a hostile crowd in Moscow. This coincided with the rise of the Solidarity Union in Poland in 1980.

In Bosnia and Herzegovina and Croatia, the gesture is known as ('Bosnian coat-of-arms') after the territorial coat of arms of Bosnia during the Austro-Hungarian reign, that is somewhat similar to the actual gesture. The gesture is also called ('from the fist to the elbow').
