k (11th letter) ↔ p (16th) — let's check systematically? Might be tedious manually.
"klmat" — maybe "format" with each letter shifted? k→f (-5), l→o (+3), not consistent.
Given the time, the most likely simple explanation is but with possible misspelling or anagram. "klmat" might be "talking" without the 'in'? No. Actually, "klmat" reversed "tamlk" — if you add 'i' and 'g' → "talking"? No. klmat-aghnyh-sdam-yabw-aday
This looks like a coded or scrambled phrase. Let me try to see if it's a simple substitution or rearrangement.
Try swapping 1st & last, 2nd & 2nd last etc. within each part: klmat: k↔t → tlmak → "tlmak" no. k (11th letter) ↔ p (16th) — let's check systematically
But "yada yada" is a phrase (aday aday reversed), "mads" is a word, "yabw" reversed is "wbay" — maybe "WBAY" is a TV station? Then "klmat" reversed = "tamlk" — possibly an anagram of "talking"?
The string: klmat-aghnyh-sdam-yabw-aday
Could be a keyboard shift (each letter typed with hands shifted one key on QWERTY)? Example: k → i (shift left), but then l → k, m → n, a → s, t → r → "iknsr" not obvious.
