Beige

In most cases, Beige is a idiom used to describe the way someone is currently acting, often in a derogatory way. The person it's directed towards usually is doing something the acuser finds to be incorrect and/or inappropriate.

The word itself is derived from the orignal term "Blowjob", and more preticuarly it's common abberviation "BJ".
