An assenine week invented for facebook-lovers, made for no other reason than to make your friends believe you've EVER been told you look like an attractive celebrity, no matter how unattractive or repugnant one might be, when your profile picture pops up on their "live feed". Wanna be cool? Don't follow the trends and stay as far away from this vomit as possible.
Example 1:

Man 1: Dude, your new profile pic's pretty hot. Doesn't look like you though.
Man 2: Thanks. I'm celebrating doppelganger week and setting my prof pic as a celeb look alike. Once, on a train, someone told me that I reminded them of Brad Pitt in the manner I itched my nose. From then on, I've seen the resemblence as uncanny.

Example 2:
Girl: So, you look pretty hot in your prof pic.

Pedophile: Thank you. I'm celebrating Doppleganger Week.

Girl: I don't know what that means, but you're sure a cutie.
Pedophile: Haha, don't worry about it.

It is not to be confused with cat fishing, which is someone that is NOT the person that they claim to have been. This is when someone looks different on social media, or dating apps than what they look like in real life. It’s the same person but a different version of them. The way they do angles in pics, old pics where they are super thin, or young, they make themselves look taller or more attractive some how....
Yo homie, show me the pics of that girl you went out with yesterday.

Bro, she pulled a doppleganger and ended up being 150 pounds.
