chain. This game involves two members versing each other until the opponent is unable to think of another word. For instance: Another language game known as nói lái is used by Vietnamese speakers. Nói lái involves switching, adding or removing the tones in a pair of words and may also involve switching the order of words or the first consonant and the rime of each word. Some examples: {| class="wikitable" ! Original phrase !! !! Phrase after nói lái transformation !! Structural change |- | đái dầm "(child) pee" || → || dấm đài (literal translation "vinegar stage") || word order and tone switch |- | chửa hoang "pregnancy out of wedlock" || → || hoảng chưa "scared yet?" || word order and tone switch |- | bầy tôi "all the king's subjects" || → || bồi tây "west waiter" || initial consonant, rime, and tone switch |- | bí mật "secrets" || → || bật mí "reveal" || initial consonant and rime switch |- | Tây Ban Nha "Spain (España)" || → || Tây Bán Nhà (literal translation "Westerner selling home") || initial consonant, rime, and tone switch |} The resulting transformed phrase often has a different meaning but sometimes may just be a nonsensical word pair. Nói lái can be used to obscure the original meaning and thus soften the discussion of a socially sensitive issue, as with dấm đài and hoảng chưa (above), or when implied (and not overtly spoken), to deliver a hidden subtextual message, as with bồi tây. Naturally, nói lái can be used for a humorous effect. Another word game somewhat reminiscent of pig latin is played by children. Here a nonsense syllable (chosen by the child) is prefixed onto a target word's syllables, then their initial consonants and rimes are switched with the tone of the original word remaining on the new switched rime. {| class="wikitable" ! Nonsense syllable !! Target word !! !! Intermediate form with prefixed syllable !! !! Resulting "secret" word |- | la || phở "beef or chicken noodle soup" || → || la phở || → || lơ phả |- | la || ăn "to eat" || → || la ăn || → || lăn a |- | la || hoàn cảnh "situation" || → || la hoàn la cảnh || → || loan hà lanh cả |- | chim || hoàn cảnh "situation" || → || chim
