A sonar bug is a bug that has echolocation and sonar capabilities. It may also refer to someone who is lanky and tall, talking non stop and very loudly, akin to a sonar bug.

The echolocation tool men use when they piss in the dark to make sure they're hitting the toilet. This involves starting to urinate and listening carefully for the sound of the urine stream hitting the toilet water. If the sound is not heard, aiming adjustments are made until such time as the reassuring sound is heard.
Joe: "Man, I got home last night drunk, went in the bathroom, didn't turn on the light and ended up pissing all over the bathroom floor."
Bob: "You should have used piss sonar to find the toilet, bro."
Joe: "Oh."

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"

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.

Whilst giving birth to an almighty stool, it enters the water of the toilet bowl and the integrity of the turd is maintained (no snap) until the bowel is evacuated. This is due to the consistancy of the log which is most likely made up of digested pork ribs with a mallasess based sauce and a pint or three of Guinness. An important phenomena is also at play, when the nard enters the water, the submerged portion of the cable becomes weightless which enables the turd to continue and reach maximum length. The cable must be maintained within a certain angle (8.5 degrees) in order to avoid cert snap.
This act resembles the use of a Dipping Sonar Array employed by Naval Anti Submarine Helicopters.
Dave, Loc and Adrian smashed a German pork knuckle, 15 beers, gelato and 5 rums. The next morning, in the Hilton Hotel room, Loc was in peril and screamed that he was doing a Dipping Sonar, Adrian asked if the cable was within limits!
