When someone mysteriously or abruptly vanishes as if without a trace. Referencing the actions of the character Albert Wesker in the first Resident Evil game.
Hey Mike, gave you seen Gary? He was here a minute ago.

Shit man, I think he pulled a Wesker.

Get the Pulled a Wesker mug.
A term used when writers bring back characters, especially villains, who have already died. The term is named after the character Albert Wesker, who died in Resident Evil, but return in Resident Evil: Code Veronica. If the dead character returns in a prequel, it doesn't count as Pulling A Wesker as the story takes place before their death and therefore they should still be around. To Pull A Wesker, a dead character must return in a sequel after being dead. This is usually done as fan service or as a surprise plot twist.

Man #2: I hope not, that'd be Pulling A Wesker
