Bae-trayal /bay·tray·al/

When a friend, sibling, or loved-one snaps you without the use of a filter or at a bad angle; a violation of trust. A major offense especially when not wearing any makeup.

Note: Proper Snapchat etiquette would specifically require the use of one of the pretty lenses (anything with flowers, stars, or a brightening, otherworldly glow are safe bets).
