&gt; &quot;cool attitude&quot;<p>Do you actually use this much, though? I had to double take because I&#x27;m not familiar with the phrase and I&#x27;m a native speaker. Typically you might use cool to in this way to describer an action or gerund, or with a prepositional phrase, or as an adverb.<p>Heck, if anything, I&#x27;d say a &quot;cool attitude&quot; is a <i>calm</i> attitude—as in, the person played it cool.
