Soypoint
A reaction of shock, hype, and excitement that involves pointing at the subject of surprise, arm fully extended, with your mouth hanging open and your eyes wide, while looking at a camera or a friend. Soypointing was first popularized by the "Two Soyjaks Pointing" meme. Soypointing is typically performed ironically.
"When that niche Nintendo character I like unexpectedly showed up in the Mario movie, I soypointed so hard."
