'man of horror' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'ear bone irritating at first' is the wordplay.
'ear' becomes 'lug' (I've seen this before).
'bone' becomes 'os' ('os' can be a synonym of 'bone').
'at first' indicates taking the first letters.
The first letter of 'irritating' is 'i'.
'lug'+'os'+'i'='LUGOSI'

'for' is the link.

Can you help me to learn more?
