I am looking for a word or an expression to describe an overreaction to positive news or positive events. Something that has to do with excessive enthusiasm like when you you are unable to control your emotions. Thanks
I don't think any of the answers provided really express over-reaction to positive news. You could still use jubilant, ecstatic or bursting regardless of whether or not the subject is justifiably excited. I believe gushing is the adjective you are looking for:
(Of speech or writing) effusive or exaggeratedly enthusiastic
Or the verb form:
To make an excessive display of sentiment or enthusiasm
And an example sentence:
"Bob was gushing over Radiohead's performance last night. I thought that the performance was good, but it wasn't really worthy of the amount of praise that he put forth."
Ecstatic comes to mind for a single word
Feeling or expressing overwhelming happiness or joyful excitement.
- When my eyes finally adjusted I was ecstatic with happiness.
- Here's how ecstatic Boston fans got the news from their morning paper.
- But I hoped he felt the same as I had, ecstatic and bubbling with happiness.
To burst into tears of joy may be a useful expression:
describes that you are unable to control your feelings because you are too happy and you cannot but show it.
beside oneself: almost out of one's senses from a strong emotion, as from joy, delight, anger, fear, or grief.
You can use overexcited to describe someone who is reacting excessively to a positive or negative situation.
"Calm down, stop getting overexcited!"
In my experience, its often easiest and most effective to just do something like this:
Michael was overly excited at the score of the soccer game.
Its a simpler approach but that often ends up being more powerful in the text. Also, if this is a situation where you can include dialog, ie fiction; then you can handle this in dialogue and have an even more powerful effect.
"Why are you so overly excited by such a simple game" she asked
This way you can set the stage in that its too much, and hammer home the point with a character's point of view.
The first word that comes to my mind is jubilant or jubilation from Latin jūbilātiō meaning wild shouting:
a feeling of great joy and celebration
Similarly there's elated/elation: joyfulness or exaltation of spirit, as from success, pleasure, or relief; high spirits.
Overjoyed, ecstatic, enraptured, delirious, rhapsodic...
For phrases, there are some idioms: in seventh heaven, happy as a clam (an old saying), on cloud nine, tickled pink/tickled to death, over the moon, walking/floating on air.*
*these make me feel really old!
If the news is of a sentimental nature, you might say the person was sappy.
When I told Jane about Billy's first steps, she got all sappy on me.
Sue told me a really sappy story about Todd's new girlfriend.
But you wouldn't say:
Randy was sappy about the quarterly projections.
You might say
Randy's reaction to the quarterly projections was overblown.
As you're asking for a description of an over-reaction to positive news, the word that first came to my mind was "obnoxious". Exaggerated reactions of joy tend to be energetic, loud, and exceedingly expressive, as if the person putting on such a display has no regard for restraint - in other words, such a reaction is typically obnoxious.
You could use American as a derived adjective, playing on the stereotype of Americans being over-the-top when it comes to celebrating.
It would be a somewhat pointed expression (a gentle (or not-so-gentle) dig at Americans), and would make more sense for contexts outside of the US.
She had a very American way of celebrating her promotion don't you think?
Effusive was the first word that came to mind. I think it's what you're looking for, if you want a single word.
