About a word that means scary
It's blood-sth，I used to remember it but have forgot it for now。
It means someone who is very scary that it makes people's blood clot in their body.
I vaguely remember it as blood-cuddling but it doesn't make sense since it means to give blood a hug.

Thank you very much in advance.

Answer

The word you are looking for is 'bloodcurdling'. It can't refer to a person, however. It is usually a sound or an image which is described in this way.

The commonest collocation is with 'scream'. For example, 'When she saw the body she let out a bloodcurdling scream.'

'Curdle' is what happens to milk when it separates out into hard lumps. These lumps are called 'curds'. The suggestion is that the person's scream was so loud and frightening that it made your blood go solid.

Answer

Blood-curdling? You can describe something as blood-curdling, but not someone. "He heard a blood-curdling scream". "It was a blood-curdling tale of murder and horror".

Answer

Maybe you're thinking "make your blood run cold".  If something makes your blood run cold, it shocks or scares you a lot.  For example, the look in the prisoner's eye made my blood run cold!

Answer

Blood-curling is probably the word you're looking for but not usually used to describe individuals.

Answer

Bloodthirsty is the only one that comes to mind.
