Not P but DFW: elbow one another

[Mike Jing]

The following excerpt is from David Foster Wallace's *Big Red Son *(from*
Consider the Lobster and Other Essays*):

This weirdness may account for some of the complex emotional intercourse
taking place between the performers and fans at the Adult CES. The patrons
may leer and elbow one another at a distance, but by the time the men get
to the front of the line and face the living incarnation of their VCR’s
fantasy-babe, most of them turn into quivering goggle-eyed schoolboys,
sheepish and salivaless and damp.

Does the word "elbow" here refer to a nudge or jostling for position?
