Pulling a doublelift is walking into an area that is not visible to you or your team when all the enemies are not in sight, resulting in finding all the missing enemies there.
Coined on League of Legends by
player Doublelift when he face checked a brush with 4 enemies in it. This was on an official stream, and since then, the Riot Games creator, Phreak, has been heard to use the phrase "pulling a doublelift" to mean face checking an area by themselves with a large number of enemies in it.
Unless you can see at least 4 out of
5 enemies on the
map or have all of your team mates with you, there
may be an ambush so face checking is generally considered a bad course of
play, using a
ward or a revealing spell being a safer
choice. Otherwise you will have successfully pulled a double lift, which will inevitably result in brutal virtual gang rape.

definition!"
