Nonparent syndrome
People, generally woman, who allow their unruly kids to run wild in grocery stores, airports, department stores and any other public places. They expect strangers to keep watch on their kids, and think they're cute while they're damaging the property of others.
The nonparent syndrome woman allowed her kid to sit on a passenger's laptop in the waiting area of a super busy international airport, while she bitched out her baby daddy on her cell phone.
