Pulling a Sebastian

When a teenager with a G-Eazy haircut takes off with a friend or family member and says they'll be right back but spends the entire weekend away from home without even texting or calling his dad.

"My son said his aunt needed some help setting up some balloons yesterday morning and I haven't heard from him since. He's pulling a Sebastian!"
