Although I have always used "He's full of beans" to mean "He's wrong/ not telling the truth" (I am from Ontario, Canada) the dictionaries I have checked only list the "full of energy" meaning. Am I crazy, or do others also use it with the former meaning?
Waiting to hear from some of you,
Seems to me that someone has developed a euphemism for "He's full of s**t"
Hi unregistered from Ontario,
It musn’t have cost you a lot of trouble if you write “full of beans” in the site Answers.com and push the key “enter.” As a result of that it comes forward the following link:
Full Of Beans: Information and Much More from Answers.com
where you might to appease yourself.
1. Lively, energetic, in high spirits, as in The children were full of beans today, looking forward to their field trip.
2. Also, full of prunes. Acting foolish, talking nonsense, as in One cup of coffee won't hurt you--you're full of prunes.
Also, full of bull; full of shit. Talking nonsense or rubbish, as in She doesn't know what she's talking about; she's full of crap. All of these expressions alluding to excrement are considered vulgar.
That's really funny.
