I don't like the phrase "Technical Debt". It's effectively lost all meaning.

I always need to ask, "what about it is technical debt?"

I've gotten a variety of responses:  
- the abstractions are wrong  
- the performance is bad  
- the technology is out of date  
- it's undocumented  
- I don't know the tech

That last one in particular when someone told me, "It's technical debt because I don't know the tech," is when I knew the phrase had lost all meaning.
