One of the ocean's deadliest and flashiest weapons in its continuing war on humanity.

The ocean rises up and sends a sweeping wall of itself onto land, killing as many people as it can. The forefront of this assault is called a tsunami.
The ocean must be held accountable for these blatant displays of aggression.

Japanese for big wave. Tsunamis can be generated by earthquakes, underwater landslides, and in rare cases, giant meteors striking the Earth's seas or oceans.
If a giant rock from space hits the ocean, the coasts and islands will be wiped off the face of the Earth

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.
We gave Brett a tsunami last night! He was pissed!

A Japanese word meaning "wave train," that causes the water to retreat on several occasions back into the ocean and striking again with an unrelenting force of liquid terror. Why? Because mother nature is a bitch.
"Look mommy, all the water disappeared! Instead of being responsible and running away like the rest of the people, why don't we go walk out onto the beach? Surely nothing bad will happen like a Tsunami!"
