Boba is called “boba” because the word comes from Chinese slang that literally means “big balls,” originally a cheeky reference to the large, round tapioca pearls in the drink.

Quick Scoop

  • In Chinese, boba is written as 波霸 (Mandarin: bōbà; Cantonese: bo1 baa3), which is slang that can refer to “big breasts” or “big bubbles/balls,” depending on context. The name was humorously applied to the oversized tapioca pearls used in milk tea.
  • Early milk tea with tapioca in Taiwan used smaller pearls and was often called “pearl milk tea,” but when some shops started using larger pearls as a marketing gimmick, those were nicknamed “boba,” and the term spread to describe the whole drink.
  • Today, “boba” can mean the tapioca pearls, the drink itself, or even similar toppings like jelly or beans, but the root idea is still those big, chewy spheres at the bottom of the cup.

A Bit Of Etymology

  • Linguistically, 波 (bo) is linked to the English word “ball,” while 霸 (ba) carries a sense of “boss,” “chief,” or “top,” so 波霸 is often interpreted as something like “big boss balls” or “top balls.”
  • Over time, the slang meaning was softened and commercialized, so for most people outside Chinese-speaking communities, “boba” just sounds like a fun, catchy name for bubble tea and its tapioca pearls.

TL;DR: It is called boba because the term comes from Chinese slang 波霸, meaning “big balls” (originally a risqué reference to “big breasts”), applied to the large tapioca pearls that became a signature of the drink.
