percs as in the actual rug p€rcoc£t? Or the f-pressed fake rox that are blue? As in, blues? Bc if the latter, I never understood why people called them p£rks when they were actually a particular imprint imitating a rocksee (the mallinkrodt brand (M box imprint)) despite the real ones actually being white with a touch of a blueish tint. Then they became unmistakably blue and fake but still used the m-box imprint and shape as mallinkrodt roc. Then people caught on yet started preferring F as they were like $1 at the time. It’s just confusing as there is already a rug called perk.
Not all blues have F though. I should mention that to be fair. Just think u should prob differentiate between blues and p’s here.
