be a slave to (something)
To be unduly influenced by or care too much about something; to spend too much or time or energy on something. Jeremy is a total slave to fashion. He can't leave the house without making sure every part of his outfit matches perfectly. I wish Sarah would relax a bit more over the weekend. She's a total slave to her job.
