A person who no matter what is the best thing that ever happened to you. Someone who you know will never turn their back on you. The most amazing person in the world! Has an understanding of your twisted humor, but knows when to be funny and when to be compassionate. All in all, if you found this friend hold on tight!
Jaqui and Mike are the ultimate besties!

Best•ie /'bestê/ noun
A bestie is so much better than a best friend. A bestie can read your mind and knows all your secrets(even the ones you probably don't remember). A bestie is the superhero of friends. This person can make you pee your pants from laughing when all the chaos in your life should really be making you cry. A bestie also is the one person in your life that knows your family(good & bad) as well as you do. One may have a few or possibly several best friends, but it is only possible to have only one bestie. A bestie always has your back and reminds you what an awesome, badass of a person you are when you need it. To find your one true bestie is truly a blessing.
Sarah and Heather have been bestie's since they were 16 years old, and love each other awful.

An adoring nickname for one you hold in highest esteem, more commonly known as a best friend. A bestie is the person who you not only go shopping with on a regular basis but also trust implicitly with anything.. besties do not come and go like waves and sandcastles, they are more like permanent marker on American Eagle jeans, they'll stay with you forever. It is much better to have one pure andgood bestie who is true to you then multiple 'besties' (even though if theres more than one t usually will not count as a bestie, technically) who are only like pants that stay with you only until you get too fat for them, or you tear them (like hurting them, and then them being all unforgiving), or just until they fade. A true bestie would stick with you through all of it, walking in when the world walks out.
Boyfriend: Hey, wanna go to the movies with me later?

You: Oh my gosh I'm sorry maybe tomorrow I've got plans with my bestie already. I would never blow her off!
