look up any word, like sweetest day:
The spotlight on the side of a cop car, because they always shine it on your dome.
I was rollin this blunt and this cop rolled through and posted his dome light in my grill

1) A candle or night light placed on the night stand so a guy can watch his girl give him dome.

2) An interior light of an automobile located on the head liner.
I like to fire up a candle as a dome light when getting head.
