爱你没没商liang
[ài nĭ méi méi shāng liang]
This username '爱你没没商liang' is more colloquial and informal. It could mean 'love you doesn't mean anything (商业 liang)' - it plays around modern slang mixed up into it where perhaps the person wanted to express loving someone does not necessarily involve ulterior motives such as business (商业 'commerce'). Here it may be expressing love in a simple pure manner devoid of any ulterior or hidden meanings like commerce or negotiation
