A tsunami is a bathroom prank that can be performed as follows:
1. Wait for one of your buddies to use a public bathroom stall.
2. Fill up a couple of buckets of water and gather outside the bathroom with other willing participants.
3. Walk into the bathroom and shut off the lights.
4. Get your helpers to start banging on the walls of the stall while yelling, "TSUNAMI," at the top of their lungs.
5. Dump the water on your soon to be ex-buddy.
6. Run away. It'll be a few minutes before he finishes up and starts looking for you.
