Refers to a "seasoned" misbehaver's having had a longer period to go astray than those under him.

Dennis the Mennis --- I mean, I mean --- Deenase the Meenase --- whatever --- however you'd spell or say it! --- is portrayed as just a little 5-year-old boy, yet he obviously has great siniority over many less-bratty children more than twice his age!
