People who think they are being "cool" or "funny" by doing a certain action or saying a certain thing, but it really comes out to look like they are uneducated morons.
A person who travels in a group of extremelyannoying people who constantly make noise and hit each other to try and impress any nearby females.
Male 1: "Man, Im about to go punch that Cool Cat in the face. Im so tired of him yelling."
Male 2: "I know, he is pissing me off really bad."
Male 3: "What a faggot."
“cool cats” basically translates to cool dude, but when the word is used it reveals more about how the user of the word views themselves. The typical user of the phrase thinks themselves a very quirky and funny individual, but this is deeply deeply untrue. The use of the word is so unfunny and awful it is physicallyuncomfortable to beat and the phrase is widely frowned upon in general
