Get the Mr. Bonar mug.
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"

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.

Get the Leopold Bonar mug.
A song made by Tobuscus in 2006 that he deleted (unknown why) it's on YouTube still because someone re uploaded it. He said in a vlog that it was a new song he was working on.
I'm so very strong
I'm a very strong man
My work out consists
Of crushing nails with my hand

I must have been conceived
By some kind of a boulder
Like a rock from Stone Henge
Leaned up on the shoulder

Of the rock next to it
And one thing lead to the next
So basically I'm the product
Of two rocks having sex

It's the only explanation
For my formidable pecks
I can crush a brick between them
All I gotta do is flex

I'm built like a robot
Out of rise of the machines
But why? I don't know
The secret lies in my genes

To help me concentrate
I crush a can on my face
And decide the time has come
For me to finally trace

The branches of my family tree
To its trunk in the past
And at last explain
This sweet, stone-chiselled ass

I surfed the net to find the
Most efficient family tracker
It racks up my relatives
Lumberjacks and linebackers

I go back generations
And hold my breath in suspense
When I see my origin
It all begins to make sense

I finally understand
These genes I'm carrying
Apparently I descended from Bonar
The Barbarian

"Bonar smash!"
He would allegedly say
Before he headbutted
Everything that got in his way

(NOT ENTIRE SONG)
