"tduuu" in Albanian (Kosovo): Not a Word

The string "tduuu" has no meaning in standard Albanian (Gheg or Tosk dialects) as spoken in Kosovo or Albania.

It appears to be:

• A typo (e.g., intended të dua "I love you", duhet "must/should", të du "that you").
• Random keystrokes.
• An idiosyncratic slang/abbreviation in a very narrow online group (not documented).

If you encountered it in a specific context (chat, social media, transcript), providing that context might allow a plausible guess, but linguistically, it is not a recognized word.
