pronoun
they; those guys; those fellows
Dated, familiar, and derogatory pronoun for a group of people, often with contempt or rough familiarity. Compare with 彼奴 (きゃつ) for singular use.
See also: 彼奴
彼奴ばらに構うな。
Don't bother with those guys.
彼奴ばらは何をしでかすかわからん。
There's no telling what those fellows might do.
Compound of 彼奴 (きゃつ, 'that guy') and the pluralizing suffix ばら (from 輩). The exact historical development is uncertain, but the form is clearly derived from older derogatory singular usage.
