Sned Uddes

Sned uddes was originally "Send dudes" but whoever was typing it had a stroke or something.

Sned uddes is sending someone a picture of yourself, but with a random character edited onto your face so that it is being covered up completely.

Guy: Hey, Sned uddes.
Girl1: wtf is that?
Guy: you uncultured swine
{guy text different friend}
Guy: hey, Sned uddes
Girl 2: {Sneds the uddes}
