Term is frowned upon within modern safety critical communications. Example being - shunter to driver "the signalman will give you the dummy in a minute" meaning the signal man will clear signal no. (XYZ) in a minute thus allowing the train to proceed.

A cheat in Halo 2 that exploits the Xbox Live network code to make a player invisible and invulnerable, allowing him to capture a flag in 15 to 20 seconds. It involves getting in and out of the passenger side of a Warthog repeatedly, then having a partner drive it to the base, at which point you take the flag, then take one step, which teleports you back to your base for the cap.
On a side note, Bungie has made dummying a bannable offense.
