This is to be occasionally placed at the end of a word (usually while intoxicated) possibly indicating a sense of excitement about the said word.
It can also be added to the end of a person's name, indicating their level of coolness. The addition of more than one "-ski" indicates that the person is more cool than that of a person with only one "-ski". However, adding too many "-ski's" to the end of a word indicates a level of retardation on behalf of the speaker. "-ski's" are best used in moderation.
