A stride that is commonly seen with those have taken a lot of ketamine (see: ktard). With reduced awareness of one's spatial position, it becomes increasingly more difficult to figure out where the ground is.

They rarely last more than 30 minutes and are most commonly seen around seedy venues near the bathroom.
Hey man, check out that girl, she's totally k-walking.
