Bāng dàománg Yuè bāng yuè máng

Bāngmáng (帮忙) means to help (bāng), or literally ‘help with busyness’ (忙). We can often say ‘help someone with something’ like ‘help him wash dishes.’ (bāng tā xǐpánzi) (帮 他 洗盘 ). However, when well-intentioned people try to help you, but they seem to be more of a hindrance than a help, you could complain to others that they bāng dàománg (帮 倒 忙).  This expresses that when they tried to help (bāng,) the opposite (dào) occurred making you busier (máng).  Another way to say it is yuè bāng yuè máng (越 帮 越 忙) is funnier: the more he helped, the worse (busier) it got.  Could be similar to “he was just getting in the way.”
