Onomatopoiea, i'd like to make it clear

is just the description of the sounds

that actions make when they strike our ear. 

Here's one example: a crash or a smash,

everyday words; a bit of a shock

when something happens to make those sounds

that often enough will cause a fleeing

like the hissing sound of someone peeing. 

Not so grating but disconcerting

nevertheless is a squelch when treading

in a mess, it's natural companion the splatter

from mouth to ground, it's just a matter

of being around such phenomena,

not that rare and probably commoner

than a puff of smoke from a conjuror's cloak

at the end of the pier with a seagull's cry

waving this pointless poem goodbye.
