”WTF want" is a tag applied when you see an illustration and think, "WTF WANT!". Became popular pretty recently.
Somewhat differently from simply wanting something when you see it, this is an aspiring emotion that makes you want to thoughtlessly automatically buy one.
Can be used together with WTF Cute, as well.
Best friend of imaginary goods, sample handmade items, whatever is very hard or impossible to actually appropriate.
▼Want = an envious thought
▼WTF Want = Woah... I WANT THIS!!! Shiiit!... Now I want to buy one! I'm buying this!!!(impulsive shopping), this nuance is big on pixiv.
Also used when the author is advertising his or her doujinshi and the viewer thinks, "I want to buy this!"
