Picture for proof
On social media, web forums, and online chat, users may use the acronym PFP to ask for a "picture for proof." PFP is typically used in response to another user's claim, especially if the claim seems far-fetched.
For example, if a user says they met Chris Evans and Benedict Cumberbatch at their local Panera Bread, other users may ask for a PFP. If the user can't provide a PFP, others are unlikely to believe them.
Example
"Totally I'll post it when I get home."

What are PFP cults?
PFP cults are groups of users who have the same profile picture. For example, in early 2021, a group of Lana Del Rey fans all changed their TikTok PFPs to be the same picture of Lana Del Rey. These users were referred to as the Lana Cult. In response to the Lana Cult, many TikTok users changed their PFPs to a picture of a hamster. These users became known as the Hamster Cult.
