A person in your life (usually friend of friend or coworker) that you get along with and enjoy overall company but will cut you down with virtually any opportunity with mostly backhanded compliments or jabs. Always roots for you to do good but just not better than them. Normally stemmed from some jealousy to any or all aspects of your life. ( similar to a hater but get along with them)
He was happy that I completed my project so quick but made sure to tell me his was faster. He is such a frenemy

Someone who acts as your friend while having alterior motives. Winston Churchill is credited with first coining this term while discussing America's involvment in WW2.

The type of "friend" whose words or actions bring you down.(whether you realize it as intentional or not) The type of friend you ought to cut off but don't cuz...they're nice... good ...you've had good times with them. U know...they're good people that you can count on to bring you down again sometime in the near future.The friend you may or may not have cornered about their quicksand like ways and keep around because "its in the past"...and so was one minute ago. The person that will continue to bring you down until you demand better for yourself.
When you ask yourself is that person my friend or enemy...they are your frenemy. Straighten em out or leave them.Don't put up with it.

An enemy disguised as a friend.

A person with whom you may have a lot of fun and/or a lot in common, who also has a vile and random dark side. These relationships are worth doing a cost/benefit analysis on. Also, limiting relationships with frenemies to non-SO relationships is a must. Why? Because it’s ultimately all about them after all, and you will need to be in a position to get away from them for indefinite periods of time. Know too, that you will probably become their frenemy as well—because you won’t be able to keep from talking behind their back. If this happens, don‘t expect everyone to get it—some will wonder why this person enrages you so much and others will wonder what you see in them.
It is recommended for your own safety/sanity that you limit yourself to one frenemy at any given time in your life.

Someone who is both friend and enemy, a relationship that is both mutually beneficial or dependent while being competitive, fraught with risk and mistrust.
Zack is John's frenemy. They get a long in the office but both of them work on internal competing teams.

A "friend" a "bad friend" who cares only about themselves. A friend who gets their way no matter the cost, and who they step on along the way. One might stay in a "frenemy" situation because they are fearful of this person. Or they are oblivious to the reality of the situation. A good way to spot “frenemies” is to judge reactions if they don’t get their own way. A frenemy will be in the wrong and wait for you to apologise. They will defriend you on social media and bitch about you, your life and most importantly your relationship behind your back with anyone who will listen. They will be mean to you or lay guilt trips to get their own way. These “frenemies” cannot stand to see you happy without them and are worried they will never have something special like you have. There is jealousy at the root of everything they do and they project a lot of hate towards other people in your life. They will interfere in your relationships and say that they are acting in your best interests. This is a lie. These are also known as a toxic friendship. If something is toxic it needs to be cut away.
Classic example 1: when your best friend ruins your relationship because they have their own selfish agenda.

Classic example 2: frenemy will bad mouth your relationship and even lie about your significant other because they know what to say to break it up and keep you to themselves
