Often abbreviated and betterly known as TD, the most famous of the 'D family.
This is when you feel a need maybe after eating, or may need to in the near future, you would take a 'tactical dump' to avoid having to dump later when there may not be a toilet or even be put in an awkward place or position, if used properly this would rule out 'power dumping
' but as the rules of 'dumping' have yet be perfected this is not the case.
Mum to son:- We'v got a long journey ahead take a Tactical Dump before we leave ther may not be a toilet stop before we arrive
Football manager to players :- take a TD before the game, dont want any of you shitting yourselves on the pitch
Im about to go clubbing better TD before i leave so i dont have to sit down in the grimey toilets in there.
