Poster Session 

When a group of academics peer pressures each another into pouring a few litres of beer into a tube designed for holding a conference poster, and passing it between them to chug from as if passing a joint.

Originated at RSS2019 in Schlappen, Freiburg.

Academic 1 to academic 2: “Hey, drink from this poster tube!”

Crowd of academics: “poster session! Poster session!”
