Okay, enough of the shitposting for now.
Let's take a closer look of what haiku really is.
Just like what I've mentioned in the first post, haiku is a type of short form poetry originally from Japan. Haiku has an easy to remember rule, that is the 5-7-5 pattern: 5 syllables in the first line, 7 syllables in the second line, 5 syllables in the last line. Do take note that the way this rule works is slightly different in its language of origin.
This 5-7-5 rule is so easy to follow that anyone can make a haiku as long as one knows how to count syllables. That's why I used this example to show this point :
(5) Haikus are easy
(7) but sometimes they don't make sense
(5) refrigerator
But as user
@Fox-Trot-9 mentioned
here, this is technically not a haiku. Haiku has another element that differentiate it from its sibling senryuu. It lies in its subject matter: traditionally, haiku portrays an image of nature. This reference to nature is what most people who don't dabble in haiku missed.
Here's an example of one of the best-known Japanese haiku :
(5) furu ike ya
(7) kawazu tobikomu
(5) mizu no oto
which means :
an old pond
a frog leaps in
the sound of water
Or better yet :
(5) An old silent pond…
(7) A frog jumps into the pond,
(5) splash! Silence again.
In Japanese, frogs are traditional symbols of the springtime. Here, the poem represents the passing of seasons, from the “old, silent” winter to the sudden arrival of spring.
TL;DR, haiku has 2 main elements: a 5-7-5 pattern and a reference to nature.
