A rare name usually given to a girl when the parents actually wanted a boy and were going to name him Earl. Girls named Erlene are typically snotty and immature and should be avoided, even if they're hot.
1:"Hey that girl is hot, what's her name?"
2:"Erlene."
1:"Oh... fuck that shit."
Very gullible but doesn't let it get to her, most possibly a hardcore Taylor Swift fan. Always takes safe decisions which can be smart sometimes. Everyone likes her and finds her unproblematic.
