The time of life when a person spends more than two hours "preening" at the mirror to get ready to leave the house. Preenage usually starts about age 12 for girls and 16 in boys, when they discover "the opposite sex" and want to be attractive.
I have give my daughter at least two hours notice before we're supposed to leave the house, because she's a preenager and takes forever in the bathroom getting ready.
