Chum 

An awesome friend. Someone you can make fun of without them pulling out your hair. Preferably someone who goes out of their way to fix your life. If you don't have a chum, your life friggin sucks.

P.S. chum is also dog food :P

"Make me an offer I can't refuse, chum."
"Lit, chum. Real lit."

You: "Ellie will never like me!"
Chum: "HEY ELLIE!"
You: "Wtf are you doing?!"
Chum: "Ellie, look into my eyes and tell me you don't like my friend."
Ellie: "Why would I do that?"
Chum: "'Cuz you can go out with him."
Ellie: "I'll think about it"
