Why is Nami's ult not called

#PunsOfDamage

Because Phreak doesn't have any influence in this

Golly Jee Willowkickers, dat thar jokez a nee slap her.

The ult wasn't called TsuNami due to the misunderstanding potential in team fights when Nami yells Sue Nami and ends up getting reported as litigation from a suit isn't possible against a video game character, so instead the summoners would get reported for liable.

Serious answer: Tsunami = "Harbor Wave" or "Tidal Wave", would have been odd with wordflow

Not Serious answer: Haaaaaaaaaaaaaaaa.

Because Nami already means wave
