Emoji bombed on bubble

I had about 20bb, same for opponent. Almighty Stack tournament on Diamond Union.

I RFI'd from button with A8o to 2.5bb

Oppenent went to 7 bb from SB, BB folded, and while I was thinking, he started to emoji bomb me with fireworks emoji.

It was hard to tell what he was trying to get me to do, but I wound up folding.

You kinda see this a lot from some players, I wonder if anyone has experience with this on the apps.
