We must all have heard disapproving relatives tut tut as they mention the amount of gobbing and dribbling that footballers do on the pitch.
England's players had better watch their mouths in Germany because the subject has caused a heated row. It all started when Willi Lemke - a former coach of Werder Bremen who is now an education minister - said schoolkids were copying the disgusting habit of highly paid players.
Kaislerslautern's Mario Basler was having none of it.
He said: "We can't carry a packet of hankies on the pitch. I'll never give up spitting. This is a contact sport not a women's coffee morning." (At this point the Dorking Ladies All Gold morning club can feel free to lob one towards the spitoon).
Volker Roth, head of the German FA's refereeing association, said it was a revolting habit to do with "a matter of upbringing" and claimed he had never seen a referee clearing his nose.
Perhaps Rudi Voller could give us his opinion. The German manager was, of course, given his own unwanted shower when Holland's Frank Rijkaard spat over him in the 1990 World Cup.
