The story

Borrowed from Dutch baas, from Middle Dutch baes (‘master of a household, friend’), from Old Dutch *baso (‘uncle, kinsman’), from Proto-West Germanic *baswō, from Proto-Germanic *baswô (‘uncle’), perhaps from Proto-Germanic *ba-, *bō- (‘father, older male relative’), source also of the English terms babe, boy, bub, bully. Later, in New Amsterdam, it began to mean a person in charge who is not a master. The video game sense is borrowed from Japanese ボス (bosu), borrowed from English boss.
