One bloody woman initially kissed trainspotter (6)
I believe the answer is:
anorak
'trainspotter' is the definition.
(I've seen this before)
'one bloody woman initially kissed' is the wordplay.
'one' becomes 'a'.
'bloody woman' becomes 'nora' ('Bloody Nora' is an expression of surprise).
'initially' says to take the initial letters.
The first letter of 'kissed' is 'k'.
'a'+'nora'+'k'='ANORAK'
(Other definitions for anorak that I've seen before include "Boringly obsessive person" , "Coat - trivia expert?" , "Jacket; nerd (colloq.)" , "geek" , "Garment; studious person" .)
