Don't put on those stinking airs - we're all colleagues here.
Tips
usage
Almost always used with the verbs 摆 (bǎi, 'put up') or 端 (duān, 'hold up'): 摆臭架子 / 端臭架子 = to put on offensive airs. 架子 alone just means 'frame' or 'manner'; the 臭 ('stinking') turns it into a clear insult about overplayed self-importance.
