Thmyl Hkr Fry Fayr Slah Blart Official

Still nonsense.

Given your "solid write-up" tag, maybe this is a known meme or phrase from a game or forum. thmyl hkr fry fayr slah blart

No.

Another thought: Could be with intentional misspelling. Reading aloud: "thmyl" ≈ "the mill" "hkr" ≈ "hacker" or "her" "fry fayr" ≈ "fry fair" "slah blart" ≈ "slash blart"? Doesn't fit. Still nonsense
