Tactical Dump 

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

Mop Bucket Dump 

The Mop Bucket Dump is one of the most heinous of all acts of defecation. The anal sphincter opens to allow a virtual geyser of liquid feces to explode from the rectum and oring. The explosive force, sound, smell and the look of a Mop Bucket Dump achieves its notoriety from the that is looks no different than if a Janitor had emptied his or her filthy, used, dirty mop bucket water out into the toilet. Pure liquid dirt. You cannot tell the difference between the Mop Bucket Dump and a dumped mop bucket.

The Mop Bucket Dump is typically the result of poor dietary choices but may also be a result of food poisoning or other gastrointestinal conditions.

Steven thoroughly enjoyed his entrée of fresh, Norwegian prawns although he thought that they might have been a little off and rancid due to the smell and tangy after taste. About an hour later, he found his ass plastered to the toilet and arms gripping the handrails as he blew a wet, steamy, dirty, brown Mop Bucket Dump. As the sweat dripped from his brow, he realized that the prawns were in fact off.
