Tight header in beautiful game (6)
I believe the answer is:
blotto
'tight' is the definition.
(I know that tight can be written as blotto)
'beautiful game' is the wordplay.
'beautiful' becomes 'b' (this could be a standard abbreviation which I don't know about).
'game' becomes 'lotto' (the UK National Lottery).
'b'+'lotto'='BLOTTO'
'header in' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for blotto that I've seen before include "Very drunk (informal)" , "Slangily drunk - ready to bolt" , "To bolt away in drunk state" , "To bolt away slangily drunk" , "Wasted" .)
