It's just a faze he's going through

A dumb-a** parental excuse to supposedly alleviate concerns and/or resentment regarding a juvenile delinquent who causes disruption and distress to those around him.

Like many of da parents and guardians of "spoiled rich kid" individuals, accompanying grownups no doubt tried to assure fellow humans who were shocked and outraged after witnessing Tronald Dump's acting out as a child dat "it's just a faze he's going through", but we can see dat is his case, said obnoxious tendencies never did get significantly better; if anything, in fact, he's actually become much WORSE in many ways.
