1. The mindset of an
individual who thinks they are very mature "for their age" and therefore refuses to see where they have room for improvement. Will
often use their alleged maturity as an excuse for the stupid, petty shit they do.
Everyone has this mindset at some point in adolescence, but if they retain this trait at age 25 it is unlikely they will ever grow the fuck up.
2. Less commonly, the mindset of someone who <i>knows</i> that they are immature, but just doesn't
give a shit.
They will most likely reach maturity
eventually because they don't play victim when something goes horrendously wrong. Because they have the self-awareness to know how their actions led to the end results, they know what to do if they want to prevent those results from happening in the future.
Typically, this brand of immaturity is more agreeable, friendly, and tolerable than the first type.
1. He acts like he knows all that, but gets defensive when someone questions the rationale behind his policies. He's 40 years old, and he's still immature.
2. He knows he shouldn't buy 10 cartons of
orange juice. He know he shouldn't go to Starbucks everyday like
hipster trash, and especially not when he barely has enough food to last him until his next paycheck. He knows he shouldn't binge watch the whole season of
Breaking Bad on Sunday night when he knows he has to get up early for work the next day. He<b>knows.</b>
But will that stop him? Ah hells no.
