When someone dosen't return phone calls or text messages. Most commonly used when trying to develop a relationship with someone.
The girl seemed pretty into me when I met her at the bar, but when I called her the next day, I got total radio silence.

When all work communication has stopped. No phone calls or e-mails are received. No one leaves their cubicle. All transmissions have ceased. Typically happens at work when holidays and/or vacation approach.
I love the days leading up to Christmas. We enforce a strict radio silence policy in our department while I shop online and send text messages all day.

the necessary, but unfortunate silence that must be called when two people who have an awesome first date, but have to part ways to different cities and become progressively less productive as they text like crazy.
I met the coolest girl, Sam, but I kept her up all night and distracted her all day with texts so she called for Radio Silence.

About that book you're going to publish: radio silence on the sale date. We don't want a stampede at the bookstore!
