That one fucker you're stuck with for the rest of your life because they know far too much for you to just be casual friends
Much like a parasite you are one in the same being except a main bitch has better taste in movie trivia
Your best friend, home skillet, buddy for life, homie home dog, home skillet biscuit, friend for life,usually of Mexican heritage, around 5 feet tall, often named Andrea because you guys are BFFS and he/she is the real MVP. All in all, your uber duper extra best friend.
