silent pimp
A Silent Pimp is a young lady who keeps various guys on the side. These can be ex boyfriends, old friends, etc. Most silent pimping is done via txt msg and/or email, 
but can also take place on websites such as Myspace.com. 

Here are a few signs that you might have a silent pimp on your hands:

1. deletes her txt msg and call history
2. constantly checks her phone for txt or calls
3. refers to ex boyfriends as a "friend"

Remember Wendy from High School? She was a huge silent pimp.
