4.
The awkward sideways shuffle to find a towel or other such object to wipe away any mess left by the one night stand with yourself.

The body is arched over so no residue falls to the floor. The sideways movement decreases wind resistance thus minimizing.

The name crabwalk is derived from the frantic shuffling side to side in an attempt to find a towel before the mess hits the floor, resembling a startled crab.

Can also be used after a bad night of KFC or cask wine when ones butt cheeks need to be clenched together as the subject shuffles sideways to the toilet in a hurry
"What was all that ruckus last night bro? Did you bring a sloot home?"

"Nah I was watching Glee and one thing led to another but I left my cum rag on the other side of the room, had to crabwalk over to find it"
