灭婊男神用大宝c

This name uses modern internet slang, 灭 (miè) means 'to exterminate/destroy'; 嫖 (piáo) means 'a prostitute/bad person'. The phrase ‘灭婊’ might be interpreted here loosely as 'slaying bad influences.' The next part '大宝C (dà bǎo C)' is possibly referring to a famous brand Dabao, often associated humorously in youth culture with 'great protection/treasure'; and it may also imply masculinity with ‘man’ earlier in sentence, but context isn't completely clear.
