[General] You are all about winning/jealous.

[arjitsharma]

I would like to know the meaning of the followings:
1. You are all about winning.
2. You are all about jealous.
3. You are jealous of your classmates. Is that what you all about.

"You are all about ..." means that it's the only thing you find important; the only reason you do something. So, someone who is "all about winning" has only that one goal; they don't enjoy the game, don't necessarily respect the rules, or even possibly the financial rewards ('game' could refer to business or any endeavour where winning is possible).

2. is wrong. You have to 'be all about' a noun. "You are all about jealousy" doesn't sound natural.
3. Similarly, this doesn't sound natural - though the grammar is correct. "Being about something" is usually an action (like winning), not an emotion. So, "You are all about revenge"; "You are all about putting other people down" would work.

Should I add only a noun and a verb after about?
I am all about winning or jealousy.
An adjective can't be addded after "I am all about" ?

Should I add only a noun [strike]and[/strike] or a verb after "about"?

For example, "I am all about winning" or "I am all about jealousy".

[STRIKE]An[/STRIKE] Can't an adjective [STRIKE]can't[/STRIKE] be [STRIKE]addded[/STRIKE] added after "I am all about"?

See above for corrections to your post.

I can't think of any context in which you could put an adjective there.

"Winning" is a noun; it's a gerund. You can't be all about win (or to win). So, without thinking much about it, I doubt you can put a verb there either.
