look up any word, like bae:
 
1.
Something that is especially cool.

Usually used as a response to a question rather than in a sentence structure.
Question: Do you want to go op shopping for dinner plates with me?
Response: Cool McGool!

Question: Can you hold my glass of red while I light this cigar?
Response: Cool McGool!

I always thought I was the only one who said 'Cool McGool' but Chris and Mel do too!
