Is there a name, term, or idiom for this gesture, the one buddy christ is doing here? Or a name similar to this gesture?
It's the "I see what you did there" gesture! :)– BiscuitBoyFeb 26, 2016 at 7:14
Point and wink comes pretty close (here), but doesn't get you the thumbs up. In fact, the image you posted shows up in that search result.
A related gesture is finger guns, which is usually playful and positive and often accompanied by a wink (here).
In fact, if you google image search "Jesus finger guns", you'll get a lot of results showing the image of Buddy Christ.

Although it's also true that a "finger gun" has gotten at least one child suspended from school in the US. Feb 26, 2016 at 14:41
I don't believe there's a single term for this. Rather, it's two gestures combined:
• Pointing and winking, indicating a personal or covert understanding
• "Thumbs up", indicating approval
