Am I the only person wondering how one waves just two fingers? I can wiggle/waggle those two fingers. I can stick two fingers up at someone (rude). I can make the peace (or victory) sign with those two fingers.
Why did you do that?
Not where I live.
Isn't this a gesture to say goodbye?
Not where I live.
Can you just answer my question?
That is an answer to your question! It's possible it's a gesture to say goodbye somewhere but now you know it's not in England. Others will have to give their opinion from other parts of the world.
I think the bigger problem is the verb 'wave'. When we make various gestures or symbols such as those in the picture, we don't normally refer to 'waving' them. Depending upon the particular gesture in question, we might 'flip', 'flash', 'shake', 'show', 'make', or even 'give' a particular gesture.
You might 'wave' your hand or some other object you're holding in your hand, but you can't really 'wave' individual fingers. You can 'wiggle', 'waggle', or maybe even 'shake' them, but not really wave fingers.
I don't know what that particular gesture in the picture is called or what it represents, (although it looks like some kind of yoga gesture or martial arts pose) so the best I can suggest is 'He held up his first two fingers." If it has a particular name, then "He made the ??? sign".
I already told you it is a gesture of goodbye.
How about 'waved arm with index and middle fingers held up'?
We've already told you, it's not one anybody knows or uses. IF it really does mean goodbye, then it's merely a product of the fictional manga work the still is taken from.
There has to be a way to say it.
Yes, myself and several others have offered a number of ways. However, just because none of them use the word 'wave', you refuse to accept them.
Ergo, say whatever you want. I have no further interest in trying to help, as I find your tone petulant and insulting.
