Kids these days.
I joined some of them. See they all live out in Hashimoto, and most of them don’t go out to places like Shibuya. Most just seem to linger around the local eat-/drinkaries around Tama. Shibuya and the likes are somewhat of a new concept to most of them.
Example: one or two of them actually did some limbo dancing out on the street. Never seen that before in Shibuya.
Swedes might do it a bit differently. Alas, I love both schools of out-of-townary.
