What is a fix it man slang?

Excuse me, could you clarify what you mean by "fix it man slang"? I'm not entirely familiar with this particular phrase in the context of slang. Are you referring to a colloquial term used to describe someone who specializes in repairing or fixing things, perhaps in an informal or non-professional setting? Or is there a specific community or subculture where this term is commonly used? Could you provide some more context or examples to help me better understand what you're asking?
