Internet memes are so timely nowadays that they spring up from pop culture the minute the source of their inspiration is released, often before many people have even seen whatever the meme is referencing.
The newest addition to this timely geek fare is the Hail Hydra meme, which sprang from a scene in Captain America Winter Soldier (no spoilers!) where one character whispers "Hail Hydra" into the ear of another character in a sinister manner.
Suddenly the internet is full of secret agents announcing their allegiance to Hydra with a whisper, in the greatest meme conspiracy of all time.
