Average bloke touring Spain (4)
I believe the answer is:
mean
'average' is the definition.
(type of average)
'bloke touring spain' is the wordplay.
'bloke' becomes 'man' (informal term for a man).
'touring' indicates putting letters inside (tour can mean to go around).
'spain' becomes 'e' (abbreviation for Espana).
'man' going around 'e' is 'MEAN'.
(Other definitions for mean that I've seen before include "Name for being tight-fisted" , "Signify; tight" , "design" , "Bad-tempered" , "Base; tight" .)
