A man whose ass is fully grown.
A very popular and time tested description of a man who is fully grown physically (which usually completely ends around age 25) and who is simply an adult, but does something an adult shouldn't do, such as not paying the bills or sleeping in too late, or neglecting his child(s). After the event, it is then considered that he is a fully developed man, and as such he is then called a "Grown ass man" as a tongue-in-cheek insult. Usually has a big butt.
