If you are bumchums with someone it does not always mean you both take part in anal love making. It also means you are really good friends. Comes from the word bumming or to bum . If you bum something then you really like it. E.g "I'm really bumming this new track!!" So a bumchum is someone you get along with really well and really like.
Person 1: "Hey Bumchum!!"
Person 2: "Haha Hey!"
Person 1: "What you been up to?"
Person 2: "Nothing Much"
Person 1: "Wow I love that new top!"
Person 2: "Thanks I'm liking your new haircut!"
Person 1: "Wanna come over my house after school?"
Person 2: "Sure!"
Person 3: "Stop bumming each other!!"
