If you are looking for high speed mass discharge a heaping teaspoon of xylitol or maltitol (what is in sugar free gummy bears) plus coffee will do the trick within 15 minutes.
Be warned that you risk serious dehydration and/or electrolyte imbalance if you try this.
What's used medically for this purpose (e.g. before a colonoscopy) is an osmotically balanced solution of polyethylene glycol, typically referred to as Macrogol.
Takes a couple of hours of continuous sipping, close to 1 liter total for an adult to get everything flushed, then you'll be discharging almost clear fluid by the end.

A bit dramatic, considering these are widely food additives to things like gummy bears in similar amounts and stories abound about their effect.
A one time event is unlikely to do too much damage unless you’re already sick.
People should generally not be taking laxatives repeatedly for a prolonged period unless they have a prescribed indication.

It’s quite common in the US to do plain old miralax and G2 gatorade for outpatient colon prep. There is some controversy about this. But there isn’t much evidence that “osmotically balanced” (the whole concept of osmotic balance is suspect for an osmotic laxative - that works because of its inherent imbalance) has any meaningful benefit other than selling something that sounds good with little evidence.
Certain sugar substitutes are laxatives. I had some DELICIOUS sugar free gummy worms from a cracker barrel that gave me the worst shits for a few hours. I only ate like 10-15 of them.
Osmotic laxatives such as lactulose need only 10 grams or so for “effect”. Standard dose of say lactulose for cirrhotics is about 20 grams multiple times per day to keep them shitting.
