"wols" was invented from the word slow. it is said to mean (by the founder of "wols") a person/object that is far from acceptable. "Wols" can be easily defined, as a closely related insult to "Retard" or "Spastic". Yet it doesn't mean
mentally disabled, just a random/
spontaneous insult, which
originally has no meaning - but people still take great affence by it. And of coarse, "wols" can also be closely related to the insult of calling some one "slow" (which is basically the same as what was spoken prior)
