Morphology

if + you + know, + you + know

The meaning — that only people with the relevant knowledge will understand — is directly signalled by the conditional 'if' plus the verb 'know' repeated; the clause literally says that understanding depends on whether 'you know'. Although used as a conversational shorthand/discourse marker, its sense is compositional and cross-linguistically paralleled, so a B1 learner who knows the words and basic conditional meaning can infer it.

Etymology

If you know, you know began as a kind of secret nod among friends and online groups: when people shared a small experience or inside joke that only some had, others would say this short line instead of explaining it. So it now means 'only people with specific knowledge or experience will understand'.
