Plug slut

Slutty female (sometimes male) who plugs their phone in and sits in a main hallway of a building, trying to attract a human of the opposite gender and have them sit with them.

Person 1: That girl over there charging her phone wants me to go sit with her.
Person 2: She is clearly a plug slut. You're the fourth person she asked. And look, here comes number 5.
Person 1: God damn plug sluts!
