Originally, Boba drinks were called tapioca milk tea (or tapioca tea latte) or pearl milk tea. When it was introduced in Hong Kong, the locals called it Boba instead of Pearl because of its shape. Boba literally means Big Pearls.
When Boba is added to the tea, it adds different texture to the creamy and smooth tea base. Boba is chewy but softer when combined with tea. It adds a fun twist to the drink.
