A haiku is an impersonal poem, at least at the first level of reading . It doesn't have a personal involvement. Nor does it express personal feeling, mood, satire, mockery.
For
that, there is the senryuu.
Formally it is a poem with the same metric features as a haiku.
It differs however from a haiku in that:
--
it lacks the mandatory word referring to the season
--it may use humor, subjects from everyday life, business, politics, love
life or sensual ones
--it is often bawdy, even crude
--the poet is involved by describing himself and stating his opinions
The demarcation line between haiku and senryuu is fluid. A slight change in the expression can move, within the same content, the haiku from one genre to the other.
Many of the contemporary haiku are in fact senryuu.
