Maybe not a western suburbs thing, more generational-based. A ripping rumour I heard years ago (from who exactly escapes me, all I remember is that they would have been in position to understand the veracity) was that a certain Vic test batsman who is universally acknowledged as extremely stiff to not have played in more tests once shit in the kitbag of a teammate whilst on an U19s tour. The teammate ended up being the national captainI played at a club for a few seasons, not too far from the Western Oval.
After training one Thursday night, while waiting for the teams to be read out, a player shit in another players footy bag.
