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."
