Cool beans is a curious phrase that uses nonsense to bring humor into a joyful exclamation. It originated in American pop culture during the late 1960s. Slang of this time is known to center around illogical phrasings of words, and cool beans is among the most durable lengthy late 60's era terms. It is used when referring to something with a positive connotation, for example, That party was cool beans..
Etymology[edit] Of uncertain origin. 1  Possibly a shortening of cup of jamoke, from java + mocha: this origin was given in a military officer's manual from 1931, around when the term first appeared.  Alternatively, perhaps a use of joe â(âfellow, guyâ), signifying that coffee was the drink of the common man.
