What can we say? He's an
morning evening person.
This is when a vampire or other critters wakes up (either from sleep or a KO) by rising like a stepped on rake, as if they had hinges in the heels that let them stand up without moving at all. This may be a Dead Horse Trope
, since I can't remember seeing it played straight outside of a comedy. When played for laughs, it's usually used to imply a given character is evil or not a morning person.
