She tells hilarious jokes and will make you die laughing. Brianna is very athletic and loves competing. She makes everyone surprised and puts a smile on everyone's face. I love this girl named Brianna!

Get the Briannamug. That one person who everyone's jealous of. Shes so perfect its infuriating. Loved by all, hated by few, wronged many. She thinks she is it all, because she gets it all. She comes off as sweet and kind, but if you are a nobody she will take out all her bottled up anger on you. She will make unnoticeable mean gestures by others, but very noticeable to you. For you are the one with the hate directed towards you. She will turn on you when you least expect it. She is amazingly beautiful, talented, and smart. She is very common in modern society. She thinks she is nice, and doing the right thing but I can guarantee if she just look down at her foot she will see someone being crushed beneath it. If you are a Brianna and reading this, I highly suggest making sure to not be rude to those around you. Silent treatment, being passive aggressive, or just plain rude will not get you far. Please be wary of those around you, and don't be mean. Your looks on the other hand will. Of which you have plenty. You also work very hard, and it pays of because your perfect. Perfect life, perfect looks, perfect brain.
-whos that girl over there?
-oh, thats Brianna
-She seems nice
-Yeah, she only ruined my life. Killed my dog, tortured my family, only to burn down my house. And yet everyone still loves her.
-But yeah, super nice...
