Used to describe that a child is not yours. Thus, making you immune to child support.

Can be traced back to as early as greek mythology.
Zeus or Posiden had a baby with Hoecles who had a son named Illegitimacus

Since Hoecles cannot prove that Zeus or Posiden are the father, Illegitimacus is therefore Illegitimate, meaning none of them have to pay child support

A term used to label children that are born out of wed lock. An illegitimate child is less likely to have a father around, indicating that the child was an accident, and will probably live a low quality childhood due to the overall detachment and lack of interest from the parents. This may also result in the illegitimate child exhibiting a higher potential for crime due to the overall lack of moral framework that is missing from the parents (if they are even present). An additional implication is a lower level of intelligence of the biological parents, and likely poverty since poor people are generally more impulsive and the lack self control required to make wiser decisions. The term is synonymous with "bastard child".
The illegitimate child was reared by trailer trash, coke sniffing parents and later grew into a social defector, only to serve hard time for its felonies.
