A man who appears physically to be grown. Whose age is of a adult but his actions are of a boy.
Signs of a grown ass boy:
Whining when he doesnt get his way.
Calling a woman out her name over a simple issue.
He wasn`t raised right.
Acts like a different person all the time.
Comes in late at night and expects you to not say nothing and hide your feelings.
When a frat boy pours beer down the crack of his frat brother's ass while another frat boy drinks it. It's like a beer bong, but instead of a funnel and hose, you use some dude's ass.
Brock: Damn bro, we got wasted last night doing ass bongs!
Brody: I know! Can you believe we did the elephant walk?
