normally, baby's chin is tucked down. Imagine the head being an oval if you look down at the top of it. The smaller back portion should present first as it enters the vaginal barrel. if the baby's chin is not tucked under, the smaller rounder portion of the 'oval' is not presenting first, and it can be more difficult to deliver for the mom. Can also refer to the baby's head being tilted to the side.
My second pregnancy was asynclitic and posterior. Big guy got completely stuck after glorious drug-free labor, and ended with a c. they even tried to manually go up there and fix him to try to get him out vaginally.
