Side Buttoned 

The term used when you call someone and they hit the ignore button on their cell phone, to avoid speaking with you.

The term originates with Nextels because they have a side button to do that.

You know you've been side buttoned if it rings for a shorter time than usual before going to voicemail.

Mark: Oh no! Greg is calling
Jessica: Don't answer it!
Mark: Good idea, I'll side button him.

Greg: What the fuck, TWO rings? Fuck Mark for side buttoning me.
