(noun) the practice of visiting as many football grounds as possible.
The final total came to ninety-seven (seventy with Newcastle). I'm only counting grounds where I've actually seen football played, which rules out anywhere I've broken into through open turnstiles or gaps in fences (Slovan Bratislava, Viktoria Plzen, Nice), photographs of building sites (Osaka, Jeju and Incheon World Cup stadiums) and grounds I've been to for non-footballing reasons (the Asian Games at Busan World Cup Stadium and an REM concert at Huddersfield Town's McAlpine Stadium). Controversially, I'm also discounting places I've seen from plane (Allianz Arena, Bayern Munich), train (Stark's Park, Raith Rovers) or taxi (Hongkou Stadium, Shanghai Shenhua) windows.
