My 13 year old son has started watching this show recently called “jojo’s bizarre adventure” where strong people punch other people with ghost like things called stands, apparently. Ever since my son has started watching he has been saying things like “noone can just deflect the 30 meter radius emerald splash” what is it, and should he been watching it? He also has seemed to pick up on his friends (who has incredibly laid back parents) stuff, and as well as jojo he also has started talking about these things called “wifus”! Please explain what all of this stuff is, and if he should be watching/talking about it.
