Stalin March
When your butthole is stretched out from a rough anal session or from using large toys, causing you to be unable to walk properly.

Most common in anal virgins who haven't been trained for no mercy by their lover.
Friend 1: Hey wanna do something tonight?
Friend 2: No, my partner gave me a harsh anal fucking, now i have to do the stalin march.
Friend 1: I've been there young man, it hurts.
