Mummy Boy - A man that is wrapped up by his girl. His girlfriend is controling or to involved with him. He seems to be dead or captured by the relationship. He may not be his true self because of his girlfriend.
Karen has a Mummy Boy, she can never let him have fun.
A complete wuss and is very sensitive. A mummys boy is the type of kid from the ages of 3 to about 33 (I've never met any bloke above!) that will not spend more than a day away from his mum. They are overfriendly and their mums actually enjoy the attention from their sons (and personally, watchin ma lil bro all over my mum makes me feel sick! Lol).
A mommy's boy is a boy or a man who has a very close relationship with his mother. As an adult, a mommy’s boy may talk to his mother on a daily basis and spend more time with her than some consider normal.
It's too bad, when you decided to marry your "mommy's boy" that you didn't realize how things would inevitably turn out.
