Redar
Similar to radar or gaydar, but for red heads. The uncanny ability for redheads to know everything about each other.
He’s a redhead like you, Kara. I can’t believe your redar didn’t go off when I told you about him!
redar
A redar is similar to gaydar but instead of detecting gays, it detects ''retarded'' people. Retarded in the sense of an idiot or somebody saying/doing an idiotic thing.
''Is he about to try to jump over that car? My redar's goin off big time.''
