哥俩 (gē liǎ) is a colloquial noun meaning 'two brothers' — specifically the speaker’s or subject’s older brother and himself (or sometimes two brothers in general). The first character 哥 (gē) means 'older brother', while 俩 (liǎ) is a contraction of 两个 (liǎng gè), meaning 'two (of people)', used only with personal nouns. Unlike formal terms like 兄弟 (xiōngdì), 哥俩 carries warmth, familiarity, and informality, often implying closeness, shared history, or joint action.

This term is commonly heard in spoken Mandarin among family members, friends, or in storytelling. It cannot refer to sisters or mixed-gender siblings — it exclusively denotes two male siblings, usually with an implied hierarchical or affectionate bond. Because 俩 already includes the meaning of 'two', you must not add a separate number or measure word before it (e.g., *两个哥俩 is incorrect). It functions as a standalone noun phrase and often appears in subject or object position without additional modifiers.
