stepsucker 

A step parent, either male or female, whom weds someone that has children from a prior failed relationship. The "stepsucker" provides shelter, clothing, food, financial support, stability, etc., etc. to stepchildren that always take yet do not give and are more than willing to live off of someone they resent and have no respect for. The "stepsucker" is permitted the obligation of having to help raise the children but are not allowed to discipline them. Any step parent that is called dad or mom by loving appreciative children is exempt from this definition.

After opening the big expensive presents and tossing the wrapping paper onto the floor the children were asked by their step parent to please pick up the trash and put it in the bin to which the step children replied, " You can't tell us what to do your not our real parent, your just the stepsucker, LOL"
