An extremely sweet and amazing girl who just wants someone to love her. She also generally has a best friend named talia and she will go to great lengths for her BFF.
The act of taking a selfie while taking a shit in the upper tank of the toilet, thereby leaving for an unsuspecting friend or foe a beef stew flush on the next use.
Once the prank has been exacted on your target, posting your photo to Facebook to share with all your friends exactly who accomplished this diabolical deed.
Dave took the last beer, so I posted my Upper Shelfie on his Facebook after hearing him flush then vomit in the bathroom
Shelsie is a beautiful, hard-working, witty, funny, and truly amazing person. You better be grateful if a Shelsie is your friend, as they will probably run for President and be very successful. And while Shelsie may be cold on the outside, know that Shelsie cares about you deeply. To all Shelsie's out there, I love you.
