A man child is a early twenties ex-frat boy who looks like a big fat fucking baby in grown man clothing. When seen in their natural habit (a bar infested with man children) they're usually talking about how lucrative their lifestyles are while in reality they're bank tellers, depositing my checks.
Man Child: Yeah bro, I'm working in Insurance; I should clear half a mil a year soon.

Andrew: You aren't doing shit. You are going to be one of those kids I hire to do all my running around, taking care of all my bullshit.

Innocent Man who preserve and cultivate "childish honesty"
or "unbiasdeness" - w.o.w.: a "(Self)Clean(ish) Person". ;)
"childish honesty" (Man-Child) is the mental feeling (unbiasedness) BEFORE kindergarten and school.

One who has a hairy chest like a sweater or fur rug. He talks about stupid shit and also his own shit. He also wear a basketball jersey(clean or dirty) at all times. He is a so called player in his own mind but is only willing to pay for women. He likes them large and is scared that his dad may spank him. His sister sleeps in his bed and he needs permission to leave the house. He is also almost 30.
Manchild Joe went to DC and leaned up against a tree starring oddly at large women. He told them he owns pizza shop all while wearing his jersey and hitting end on his phone because his dad calls non stop to spank him. Manchild joe is one who stands in the corner and grunts at women. He makes them scared.

Manchildren are adults that engage in childish behavior too often -- eg. play videogames, collect figurines, watch cartoons meant for children -- instead of getting a job, studying responsibly and moving out of their mom's basement.

The older they get while refusing to grow up, the more pathetic they become. Manchildren can also be female.
Only manchildren play videogames all day.
