Avoiding interactions with
people by looking at
one's phone.
It can be hard to determine, but is obvious if one looks at their phone as they see someone approaching.
Variations of this include talking on the phone or having earbuds in to discourage
people from interacting.
"I was walking back from
library and this girl pulls out here
phone as
soon as she sees me, then puts it away and looks up when I walked by." "Classic phoidance."
