Sven Lemming 

Sven was a fictional employee created to allow people add an extra desk to your work area for people visiting from another office(hoteling workspace) at The Boeing Company circa 1990s

Usually a reference to the open work space or a missing person or mythical employee.

Use Sven Lemming's desk, he's not here

Oh, he's playing golf with Sven Lemming

Call for Sven Lemming, Call for Sven Lemming

lemming 

A member of a crowd with no originality or voice of his own. One who speaks or repeats only what he has been told. A tool. A cretin.

"Ya think he'll do it?"
"He's a lemming, he'll do anything he's told."

Lemming Train 

Online first person shooter battles. Groups of players follow another rushing player across an open battlefield without reason or understanding of tactics and get themselves killed very early in battle. These inexperienced players follow the monkey see monkey do mentality thinking they are safe by numbers. See Lemming rush.

Look at all those guys rushing up over the ridge and getting killed. Such easy pickings. What a lemming train.
Half our idiot team thought it would be great to break off and lemming train across the open field. Now it's just our 5 tanks againt their 12 >:(
