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).
