A demand made on internet forums to post images of a currently discussed topic. A lack of images is tantamount to a lack of proof; hence the consequence is "shens" or shenanigans. See pics or stfu
Roughly translated, it means "show images of said topic or I will consider your claim to be false"
Cantankerously: OMFG Ellen Degeneres was found dead, drowned.
Catmando: Pics or shens.
