2. Vulgar Slang (Adverb):

Advanced Usage

  • Nó biết đéo gì đâu. (He doesn't know a damn thing.)

Variants and Related Words

• Đếch: A slightly softened, slang variant of "đéo," used with the same meanings but sometimes perceived as slightly less harsh. It is still very vulgar.

Synonyms

• To fuck: (for the sexual verb).
• To not care at all: (for the verb of indifference).
• Damn / Bloody / Fucking: (for the adverbial intensifier).

Important Note on Usage

"Đéo" is an extremely coarse and offensive word. Its use is considered highly impolite, vulgar, and deeply disrespectful in almost all social contexts. It is common in angry confrontations, among very close friends in casual settings (where it may be used for emphasis without serious intent), or in certain forms of expressive art (e.g., music, gritty literature). Learners should avoid using this word entirely, as misuse can cause severe offense.
