«شَايِبْ وِعَايِبْ»

This rhyming saying criticizes someone who has reached old age yet still behaves in ways that bring real shame, not mere mischief. The grey hair is meant to signal maturity and sober judgment, so foolish or improper acts from such a person stand out as especially disappointing and hard to excuse.

It also carries the idea that age demands a certain dignity. When an elder ignores what his years should command, whether through ignorance that youth might excuse or through unbecoming deeds, the remark points out that he has failed to honor his own white hair.

Apply it to an older person whose behavior seems foolish or improper for their age, such as reckless conduct, unseemly antics, or a lapse in dignity. It is a sharp, disapproving remark, usually said about someone; addressed directly to an elder, it can sound insulting and disrespectful of their age.
