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"?
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
Could it be a phrase where vowels are removed? klmat → without vowels? "klmt" — no. But "yada yada" is a phrase (aday 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. "klmat" might be "talking" without the 'in'
k (11th letter) ↔ p (16th) — let's check systematically? Might be tedious manually.
The string: klmat-aghnyh-sdam-yabw-aday
