Boner sonar 

Ability to detect erect penises at a distance beyond what the naked eye can see.

My Boner sonar always goes off the charts when I walk past the spooky old house.

Bonar Sonar

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"

Sonar Bonar

A boner capable of detecting nearby genitalia via a method of clacking ball sounds.

I was so horny, but thankfully, my sonar bonar led me to the closest prostitute.

My asian buddy got lost in the forest, but thanks to my sonar bonar, I found him by looking for the smallest genitals in the area.
