(n) pastel rainbow pants; a highly contagious disease that has spread through the K-Pop community with devastating effects, such as the before and after Lucifer dances by SHINee and Infinite's music videos.
I really wanted to perform Lucifer by SHINee but then SHINee caught pastelpantaphilia and I don't want it to spread.
I really hope Infinite burns their pink and baby blue pants to stop the spread of pastelpantaphilia.
Friend: Wow, that band looks so cheesy! Look at those awful pastel pants!
KPop fan: They used to be cool, before they caught pastelpantaphilia.
A gamer who likes pastel aesthetics usually has a pastel setup and surrounds themselves with the pastel theme. Their theme could be all the pastel colors or just a specific color or two but it is usually just very light colors. They are usually into soft cute things but can be found playing any game.
There are a lot of cute pastel gamers nowadays.
My friend is a pastel gamer. She has a lot of plushies and plays animal crossing.
