Definition 2: when your girl gives birth but you're not in need of a baby so, you replace it with a baby of another race, blame your girl and dip.

A replacer is a friend who can only have one best friend at a time. So one day, they're best friends with one person. And if they see a new person walk by who seems nice they go meet them. Just like that, the previous best friend gets replaced. Or kicked to the curb, if you will.
"Hey Replacer." said Maya. "Replacer? Why are you calling me a replacer? I don't replace people." said Raymond. "Oh really? We were best friends until you met Muziq. I got replaced. By you."
