I've just got to know that the word 'housewarming' means not 'heating the air inside the house' as one could assume, but 'moving into the new house' . Rather funnyDoes anyone know some other words of this kind?

I am not sure if these words look like what you wanted to see in this
topic. Anyway, I like them.

Nine-to-fiver - is a person working in the office from nine a.m. till
five p.m.

Brown-bagger (Amer.) - a person who takes his food into the office
(in America it's usually in brown bag) for the purpose of economy or
because of keeping to a diet.

As far as I understoщd your 'secret' meaning is called a metaphor.

There are plenty of them in Engish.
Here is my contribution:

to moonlight - to make money on the side, to take extra work.

I've been had - be deceived, be fooled (as in Russian меня поимели )

to cry blue murder - cry for a help

couch-potato - the guy that always stays at home when you invite you somewere

It seems that words I'm speaking about are not metaphors... Though, I'm not sure. I mean the words that can not be understood properly without the exact knowing of their meaning.

A word can not be a metaphor. A metaphor is a stylistic device applied to word and expressed by its meaning.

The words you're talking about can't be understood properly just because their meanings shifted due to the likeness or analogy with their literal meanings.

Such process is called metaphorization.

Don't you think these words are a kind of neologisms? You really will not know what they mean unless you find them in the dictionary or ask a native speaker about the meaning. Very often you willhave to guess or just analyse the word and its components to grasp what it means.

Your supposition is rather considerable. Metaphor and neologism sometimes coincide in process i.e. the use of old words in a new sence. But mind that neologisms appear when a new sence is needed that never existed earlier and have nothing in common with speech expressiveness.

Here are some more I came across:

to shoot Niagara - to determine oneself to a desperate attempt/action

green-eyed monster - jealousy (in the meaning of painful suspicion of the faithfulness)

Freeload - халява (sorry, I don't know how to put it properly in English). I stumbled onto the following example:
He always eats dinner with us but he never invites us for dinner, he likes to freeload. (...любит пожрать нахаляву).

Well, I am not quite sure that neologism comes to a language when a new meaning appears... Would you say that there wasn't a notion "бедный, нищий" in English before the neologism "disadvantaged" appeared? And the word paytriotism... And so on and so on... Anyway, it is not so important for me how we can call these words or the ones which Hilda showed us in the beginning of the topic. What I really like is to learn new words and their new unexpected meaning, and the feeling when I succeed in getting what they mean.

Somewhen any word was a neologism, right?

By the way, will you give me the link where 'disadvantaged' is used in the sense of "бедный, нищий"? Anyway 'disadvantaged' is not a proper example since it was formed by the use of the prefix 'dis-' with a well-known meaning.

As for patriotism, this is of course a neologism but there are no secret meanings in it.

show-stopper - гвоздь программы
clutch-hitter - палочка-выручалочка
on a hunch - intuitively

Looking forward for yours...

Well, as for these two words: disadvantaged and paYtriotism.

Recently I started some king of investigation about English lexicology and such things like neologisms, metonymy etc. In one of the articles word “disadvantaged” was cited as the example of neologism, when a known word acquires a new meaning. In that case it was the meaning "бедный, нищий" (in other words, a person without enough money to have the advantages which a wealthy one has).

And as for PAYtriotism (not patriotism) – I think you can guess the meaning by yourself )))

OK. I see.
Pity you don't remember the name of the book with 'disadvantaged' in a new sense because I can't find it even in new edited dictionaries.
