胸口有料不信摸摸裤裆有货不信试试
[xiōng kŏu yŏu liào bù xìn mō mō kù dāng yŏu huò bù xìn shì shì]
A rather colloquial phrase, this name literally means 'If you don't believe me, try checking yourself' which sounds quite humorous and somewhat crude. But behind its cheeky tone is likely meant to suggest a confidence and assurance in what the user has to offer or express - whether metaphorical wisdom and humor, or simply bold self-assurance and challenge towards skeptics.
