Keeping her green

Pronounced "keepin' 'er green"

While working from home, deliberately moving the mouse or pressing keys solely to keep Skype for Business status as "Available" (green) instead of "Away/Inactive" (yellow) so that your boss thinks you're working

Person 1: "I Skyped him 3 times today, I don't know why he isn't responding, his status is 'Available' on Skype"
Person 2: "That's because he's keeping her green, the guy is playing Runescape all day today and he just wiggles his mouse on the work laptop every 15 minutes so his Skype status doesn't become inactive".
