"Mamma's boy" is a term used to describe a man who excessively relies on his mother to make decisions and take care of him. However, there are several synonyms that can be used to describe a man who has a strong relationship with his mother. These include mama's angel, mama's darling, mama's favorite, mama's prince, mama's pet, and mama's hero.

It is important to note that while these terms may be used in a lighthearted or endearing manner, there can be negative connotations associated with the term "mamma's boy".
