tactical poo

A tactical poo (abbreviated to TP) likens a tactical chunder as a waste disposal system.

Normally referred to as a TP in public

A TP allows one to dispose of unwanted lunch, breakfast, dinner or snacks, allowing for more room to be made and therefore more food can be consumed.

Both: "time for a TP"

"I'm so glad I had that tactical poo, now I have room for desert!"
