If you're forever alone, there's nothing that grinds your gears more than a happy couple. You don't have to take it out on your friends and family anymore, though, because this girl on Instagram is doing it for you.
"Ah, love. It makes the world go round. Unless you're me. Then you just lurk in the background of cute couples, but hey." This is the only bio Third Wheel Extravaganza needs. She doesn't care if it's your engagement party, your wedding, or your pregnancy announcement. No one is safe from her signature deadpan grimace.
Though she hasn't even revealed her name yet (unless her name is actually Third Wheel Extravaganza because she's that committed), her page has become and international sensation. Finally, all the third wheels of the world have found salvation from the onslaught of Instagram couples, and she is their patron saint.
