Etymology

Origin of bop¹

1945–50, (be)bop

Origin of bop²

First recorded in 1935–40; variant of bob ³

Explanation

If you bop your little brother, you hit him lightly. If you do this, he's probably going to bop you right back. The origin of the word bop is imitative: bop sounds like the noise your hand makes when you bop someone or something. You can also use bop to mean bebop, the fast-tempo jazz that became popular in the 1940s, after the swing era. The word comes from the jazz tradition of singing nonsense words like bebop and rebop.
