There's a guy that is friends with the family that my mom went out with. He broke her heart so I'm looking for some sweet revenge ;) Is there anything I could put in his drink that would make his poop a lot or throw up? Any ideas are great. Thanks!
Although this seems like a harmless prank people pull in movies - it's actually assault, an actual crime to do this. Besides just being illegal anything you put in a person's body without their knowledge runs a risk of seriously harming him.
What if he chokes on his own vomit and suffocates? What if he loses control of his bowels in the middle of driving along a road in the middle of nowhere or gets into an accident, or passes out because of the dehydration? What if he as a medical issue you don't know about and what you give him causes a stroke, or heart failure, or a deadly allergic reaction?
It might seem unlikely, but it's likely enough that it's not okay to do anything like what you suggested here.
