Given the playful nature, I'll guess it's a after removing hyphens: klmataghnyhsdamyabwaday reversed = yadawbaymadsyhnyghatamlk — no.
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.
But "yabw" reversed "wbay" — maybe "wb" as in "web" + "ay" → "webay"? Unlikely.
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"? klmat-aghnyh-sdam-yabw-aday
Could be the phrase is: but with cipher.
The string: klmat-aghnyh-sdam-yabw-aday
Let's try reversing the whole string before splitting: klmat-aghnyh-sdam-yabw-aday reversed = yada-wbay-mads-hynhga-tamlk — still "yada" and "mads" appear but not fully clear. Given the playful nature, I'll guess it's a
Could it be a phrase where vowels are removed? klmat → without vowels? "klmt" — no.
klmat → jklzs? no (k→j, l→k, m→l, a→z, t→s) → jklzs — not obvious.
Try swapping 1st & last, 2nd & 2nd last etc. within each part: klmat: k↔t → tlmak → "tlmak" no. But "yabw" reversed "wbay" — maybe "wb" as
k (11th letter) ↔ p (16th) — let's check systematically? Might be tedious manually.
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.
This looks like a coded or scrambled phrase. Let me try to see if it's a simple substitution or rearrangement.
