In a way that is too much like acting — showy, exaggerated, and clearly done for an audience rather than felt. If someone sighs stagily, they make sure you hear the sigh. If someone stagily wipes away a tear, the tear may be real but the wiping is a performance. The judgement inside the word is that the behaviour is not natural: on a stage, an actor has to be big enough for the back row to see, and someone behaving stagily is doing that in a living room where nobody needed it. It is mostly used about small physical actions and manners — the way someone gestures, whispers, pauses, rolls their eyes, or delivers a line. It usually goes with a verb (stagily raised an eyebrow, stagily lowered his voice) rather than with an adjective. The tone is critical but usually light — amused, teasing, a bit dry — rather than angry. Sometimes there is no criticism at all and it simply describes a deliberate, theatrical style, especially in writing about theatre, film or design. Honestly, this is an uncommon word, and much more written than spoken. In everyday talk people say 'he was being so dramatic' or 'she made a big show of it'. The adjective stagy (also spelled stagey) is the more common form of the two, and even that is not frequent.

做作地、很戲劇化地（誇張得像在演戲給人看）。日常台灣人多半直接說「很做作」「很浮誇」「演給你看的」。
