juice

n. The weight of a given node in some sort of graph (like a web of trust or
a relevance-weighted search query). This appears to have been generalized
from google juice, but may also derive from black urban slang for power or a
respect or from "drinking the kool aid" (having bought into some belief or
system). Example: I signed your key, but I really don't have the juice to
be authoritative.
