たまらない
たまらない · tamaranai · JLPT N3 · expression
intolerable
堪る tamaru = to endure, + nai = not: can't endure it
たまらない is the negative of 堪る (tamaru, to bear or hold out), so it literally means you can't hold out. It also means irresistible, as in this smell is tamaranai, so good you can't stand it. A verbal hook from the sound: tomorrow? Nah, I can't bear another day.
