while in the midst of giving a slutty girl a blowjob you proceed to ream your cock down her throat, as your cock goes deeper you will hear her gag quicker and quicker the deeper you go. similar to the sonar effect.
i was with this dumb slut lastnight and she wasnt sure if she could deepthroat, so i did the sonar test on her!

First, you must be drunk to perform the sonar slide. Then you have to find a girl and fuck her in the butt with her forehead on the ground. Right when you skeet you throw up down her back, yell "SONAR SLIDE" and grab your clothes and run.
Yo man I was so wasted last night that I sonar slide'd a girl. She was so pissed I had to run out of the room with no clothes on.

When a guy breaks up with you and still kind of likes you senses that there is other dick trying to invade what was once familiar and proceeds to go on a like all current status', photos on social networks to try to gain his ex's attention once more. But beware it's a fantasy.. Don't give in.. Keep dating
Aned says: "man that dude has dick sonar it's like OMG I sense other dick around.. I gotta step in and ( fuck I miss her/him) pay attention to me!!!!!!!!"

Me: so what you are saying is it's a" check up " and they are experiencing the "want what you can't have" feeling.. Huh, thanks for the insight girl !

Whilst in the cubicle when someone else walks into the bog you listen intently (turn on your bog sonar) to determine what they are up to, in order to plan the intensity of your next squeeze, volume of groan during the squeeze, ferocity of wipe and subsequent exit from the trap to avoid exposing yourself to the defecation interloper.
I was taking a massive shit in trap 2 when someone walked in the bog mid squeeze. I had to turn on my bog sonar to make sure he'd finished before I could carry on and finish. Couldn't let him know it was me groaning and letting out that stench I'd get grief all afternoon in the office.
