It's a type of Japanese poem that is similar in format as the haiku.
Okay, this is not English class, but I know you wish to be enlightened. If not, you will, by golly. Or, you can simply scroll down to the poems. My education of all things haiku came last night when I finally wrote the last line to my haiku-in-progress. I felt that it wasn't really a haiku.

In short, the haiku and senryu are three-line poems composed of 17 syllables. The pattern is five syllables in the first line, seven in the second, and five in the third. Haiku poems are about nature; no mention of human foibles allowed. Senryu poems are about human nature; no reference to the natural world at all.
Now, you know. It didn't hurt, did it?
Here's a true haiku by Basho Matsuo, who is said to be the first great haiku poet. He lived during the 17th century.
An old silent pond...
A frog jumps into the pond,
splash! Silence again.

My body says old!
