Get the baby man childmug. 
an adult who acts immaturely and well, childishly. man children have lots of overlap beetween neck beards. typically they live with their parents and are unemployed, but there are exceptions. (though most who are employed are probably flipping burgers) they often have horrible social skills as well. man children often are obsessed with some kid's cartoon or pop culture stuff. they fill their rooms with toys, action figures and more. overall, man children are leeches to society. just like actual kids. even kidnapping them is harder to do than with children. you have a tub of lard to deal with after all. thus you need to upgrade to adult sleeping to get the job done.
mother: my god! clean your room! you have no job. you could at least clean your room!
man child: no! i gotta watch the new teen titans go episode!!!
mother: you are such a man child, son!
