when a girl already has a boyfriend but she gives her number to guys that she meets and flirts as if she were single. she's basically branching off from her boyfriend and establishing backups.
yo dude I saw your girl at starbucks giving her number to some guy. I don't think she saw me. it looks like she's monkey branching, you should dump her.
