Text effects WITHIN iMessage bubbles

Once upon a time not too long ago, whenever I would text a friend of mine and include her name, iMessage would apply a special effect TO her name. It was quite dramatic and cool.

The best way that I can describe it would be that after I typed in her name, my phone would emphasize each letter in a slightly different color and size, and after it had reached the last letter, it would go back and very quickly, from left to right, add what I would almost call a sparkle effect to her entire name. My phone stopped doing this, and if I have to guess, it was after an iOS update had been released.

This is all very non-sensical and not important at all in the great scheme of things, but if anyone has an idea HOW this was purely-by-accident activated by myself, and if it is still available, it would stop bugging me.

To be clear this effect wasn't applied to all words within the text bubble, just her name.

TIA!
