Sneed - another word for 'Cool'

Is this really cool?

This week we have been discussing the term 'Cool'. What is cool and what is uncool? Who decides what is and isn't cool? In my blog I have started to use the word sneed, which is not an actual word and to be honest I don't have a definition for it. However I guess the word 'sneed' relates to the word 'cool' when using the term as I have done in my blog to find 'sneedingly good' performances. But what is a cool performance??
