你是逗比请来的救兵么
[nĭ shì dòu bĭ qĭng lái de jiù bīng me]
Literal translation would be: 'Are you the reinforcements invited by funny/foolishness?' The user seems like he is joking and trying to convey a tone of mockery, surprise, or jest towards others. 'Dou Bi,' a term for someone silly or foolish, is commonly used among Chinese youth online to create humor. Thus, using the idiom humorously to imply a rescue attempt made due to mischief.
