What is the kaioken-like red aura produces by Chichi when she's mad? In episode 75 of DBS, Chichi produces a strong red aura when she was angry. Similarly in DBZ, Chichi seems to produce the same red ki when Maron called her an old lady in the Garlic Jr. Saga. It's unlikely to be a kaioken because the dragon ball dedicated wiki doesn't include her in the kaioken users list. What exactly is this red aura? We don't see it on other Z Fighters except for Goku.
It's just for humor. This is seen in a lot of anime, including one piece, where female character appears to be stronger than the protagonist as well when angry, and proceed to beat them up. Don't think too much into it.
