Holding in all of the aggravating, stupid, child-like statements inside of your head until you feel it is the right time to let them out.
Mature person: “So tell me why you chose to be extra aggravating today”
Childish person: “Because you are feeling better and now that I know that, I can return to my childish ways”
Mature person: “Oh, i’m not surprised”

A Childish Flambino is when you take someone's name and turn it into a childish schoolyard-style taunt.
Childish Flambinos of famous athletes:
Aaron Judge: Errin' Fudge
Lionel Messi: Lyin'Hell Messy
Mesut Ozil: MessIt NoZeal.

Like a 3 year old.
Not being okay with some spoiled rotten mollycoddle trying to walk over somebody isn't a childish thing to get angry about, it's a legitimate thing to get angry about and stay angry about, especially when the one that got angry knows the mollycoddle takes nothing seriously and holds nothing sacred, and lies about everything and has told the one they got angry they needed to wake up and fight.
