Prematch Poo

Prematch Poo, a poo which takes place just before an event, preferably sporting event.
The prematch poo has many advantages including

1) Not needing to piss or shit during the event.
2) Being that slight bit lighter.

This tactic was founded by Burnley FC manager - Shaun Dyche
But adopted by the Italians when winning the World Cup.
