Coffin Mom
A US term for any mother who decided to have a child later on her life. Particular pleasure should be taken from the fact that the child is more likely to see his mother die long before yours, affording you many years of actual "dead mum" jokes before you have to deal with the trauma yourself.
"How old's ya Mom?"
