Wikipedia: Curtain call
A curtain call (often known as a walkdown or a final bow) occurs at the end of a performance when individuals return to the stage to be recognized by the audience for their performance. In musical theatre, the performers typically recognize the orchestra and its conductor at the end of the curtain call. Luciano Pavarotti holds the record for receiving 165 curtain calls, more than any other artist.
Sports curtain calls
Athletes who also perform well may return to the field of play after a big play or at the conclusion of the game for recognition. Professional baseball players usually take their cap or helmet by the brim and hold it in the air. According to baseball historian Peter Morris, in May 1881 Detroit fans cheered a home run by Charlie Bennett until he bowed to them.

On the contrary, it wished to express its hearty disapproval - and disapproval, not compliment, was the origin of the actor’s curtain call. A roar of disapproval which would hold up a play until the wretched delinquent came out to face the music—the hoots and the hisses of the disappointed, and it might be their missiles as well. In brief, an experience the actor desired to avoid.
