Extremely / like crazy (…得不得了)

Structure Adjective + 得不得了

Adjective + 得不得了 (… de bùdéliǎo) is a very expressive degree complement: it marks that a quality reaches an extreme, "incredibly, like crazy". 今天热得不得了 = "it’s unbearably hot today". 孩子们高兴得不得了 = "the kids are over the moon". 不得了 (bùdéliǎo) on its own means "terrific, extreme"; here it intensifies the adjective.
