Burmese water trap

A way to sabotage someone by placing a folder or other similar flat surface on the top of a bottle/glass filled with water (or any other liquid), flipping the liquid-filled vessel upside down, and then carefully sliding the folder out from beneath, leaving the overturned container on the desk/table/ect. of the victim. Carefully poking holes in the bottom of the receptacle after setting the trap up will also increase the damage done by the Burmese Water Trap, as well as remove the likelihood of your target containing a percentage of the water within the vessel after triggering the trap.

That waitress was extremely rude, so I put her tip inside of a Burmese water trap.
