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"?

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.

But "yabw" reversed "wbay" — maybe "wb" as in "web" + "ay" → "webay"? Unlikely.

The string: klmat-aghnyh-sdam-yabw-aday

Could it be a phrase where vowels are removed? klmat → without vowels? "klmt" — no.

"klmat" — maybe "format" with each letter shifted? k→f (-5), l→o (+3), not consistent.

Could be the phrase is: but with cipher.
