def:manny

If you search for my nickname on urbandictionary.com you'll get the following results:

1. An overweight male who has an overbearing wife who controls his thoughts and actions and is deprived all forms of entertainment and enjoyment and forced to live a life of servitude.

I feel bad for Greg because he has turned into such a Manny. 

2. A male nanny. From the same roots as murse, a male nurse.

I felt uncomfortable letting a manny babysit my kid.
