Radar Mode 

The act of removing one side of your ear/headphones, so that you may hear the sounds of your computer, whilst remaining aware of the sounds around you.

Radar Mode is often initiated when viewing pornography in a house that is not empty of other occupants.

Adam: It must be annoying having your parents staying over this weekend.

Connor: Yeah, I've had to use Radar Mode all weekend!

Radarmode Masturbation 

When you masturbate at your computer, wearing headphones, with one ear exposed so you can detect any sounds around you as well.

Whoa, that was close, Dad almost caught me jacking off! I'm going to try radarmode masturbation so I can hear when he's coming into my room.
