planned hammer

Basically a pre-scheduled bender. It's a result of turning 30 and having to plan your hangovers around other obligations like your job or your kids.

Sarah: Hey Kimmy, can you take my morning shift at IHOP on Sunday? I have to go to church that morning.

Kimmy: I'd love to, but I have a planned hammer on Saturday. I'm going to a kegger at Lorenzo's house, and i plan on getting white girl wasted.

Sarah: Can I come?

Kimmie: No way churchie.
