Ten Bob Head

This phrase has been used in Liverpool for decades.
1 Adjective. Description of a poor attempt to direct a football goalward with the head.
2. Adjective. Description of person who made the poor attempt to direct the ball goalward with their head.
Based on ten bob being a 50p piece, ball has spanged off one of the vertices of the 50p piece which is metaphorically on the footballers head. Ball heads off at a wild angle to that which was intended.

" That was a proper ten bob header mate"
" The state of that, you ten bob head!"
