This term was used by an old Senior Developer of mine but for the life of me I can't recall it. The context of the conversation was that he wasn't necessarily more skilled than an Intermediate Developer, but he had more knowledge and experience in particular areas. In a sentence, it would be used like,
I have more _____.
My brain keeps giving me the terms
region knowledge and
area knowledge, and I feel like those may be close, but are definitely not it.
