Boo Basket

a trend on TikTok where people (usually young women) purchase an assortment of cozy items and put them in a basket, these baskets are typically themed around a season or aesthetic, namely fall, hence the name "boo basket", but not all of them are fall-related. This trend seems to capitalize on the "overconsumption-core" trend on TikTok, where creators will buy excessive amount of items, usually beauty or bath products, and make an aesthetically pleasing video displaying the often alarmingly sized collections of said items, neatly arranged and color-coded. Essentially, it's just another iteration of people buying cutesy items they don't really need for clicks.

"my sister got me a boo basket for Halloween and I don't know how to tell her that I already own most of the things she got for me"
