Waluigi debuted in Mario Tennis in 2000 as Luigi's tall, scheming rival and Wario's doubles partner, quickly becoming a fan favourite for his theatrical whining and exaggerated reactions. Clips of his voice lines have circulated for years in gaming edits and meme compilations, where his insincere tone is borrowed to comment on other people's wins. The short 'nice' line survives because it needs no context, viewers recognise the character instantly and understand the praise is not entirely genuine, making it a reusable reaction across Nintendo fandom.

Waluigi says 'nice' in his smug nasally voice from the Mario games, a short clip used for sarcastically praising a lucky play or a questionable success.
This is Waluigi delivering a single drawn-out 'nice' in his unmistakable high, nasally whine, equal parts impressed and annoyed. The delivery is stretched and smug, as if he cannot believe what he just saw but has to admit it worked. It lands as instant sarcasm because Waluigi is Mario's lanky, jealous rival who rarely praises anyone sincerely. Dropping it after a clumsy win or an accidental success makes the moment feel both celebrated and mocked at the same time, which is why the clip works so well as a quick reaction.
