When one sits around in a parking lot after school, blasting their car stereo really loud, subwoofers and all. This generally irritates those living nearby, who often will express their 'gratitude' by either calling the cops or reducing the number of functional body parts of the perpertrator.
That bastard Harvey was subwoofing from the parking lot next to my apartment last night. I was finally able to get rid of him when I lobbed an anvil at his car from my window.
sitting in your car bumping your jams with your homies after school in the parking lot but not driving. you just sit there and act cool with the windows rolled down. you want everyone to know how awesome your system is.
"hey guys, did you see jon and billy subwoofing in the parking lot? it was mad cool. they have a system."
The often inconsiderate action of playing a car stereo at full blast simply to annoy those around you. Typically the object is also to make the rearview mirrors of those around you vibrate in addition to your own trunklid.
Yo, that punkass was subwoofing so fuckin' loud at the red light I couldn't see my own reflection in my rearview!
A dead drop is a location used to secretly pass items between two people, without requiring them to meet.
Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.
A common place is to duct tape the item to the underside of a toilet cover in a public restroom.
A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.
"The dead drop is the restroom toilet at the Gulf station at the corner of Commercial Ave. and Georges Rd."
