What does a fish bump and explosion mean?

[wondering_guy]

i mean some people do just fist bumps and some others do fist bump and add right after a hand open and explosion sound.

is there a meaning for this?

i mean I know a fist bump is a sign of some kind of respect but what's the other if there is any meaning too it?

It's a good way of connecting, especially if there's no time to talk and people are in hurry. It also means that those people doing the act are pretty close to each other.

It's just a friendly gesture like greeting a friend with a hug. I don't think there's any particular meaning to it.
