An imaginary device that allows a person to recognize when another person has a boner--or has recently seen an attractive person.
Usually held by guys when with other guys. A constant
beeping sound is a classic sign of someone's
bonar sonar being
activated.
Note: The bonar sonar tells when other people have a boner, not yourself. So if person A has a boner, person B would be notified by his bonar sonar.
*An attractive female walks by*
Friend A: (Stares at ass)
Friend B: "Wow, my Bonar Sonar is going crazy right now"
Or
*Friend C is talking to attractive female*
Friend A: "
Beep,
beep, beep"
Friend B: "What?"
Friend A: "Look"
Friend B: "Haha. He's a player"
