boombox(redirected from a boom box)
A large, portable radio. The stereotypical image of hip hop in the '80s is a guy walking down the street with a huge boombox on his shoulder. I can't hear myself think, thanks to the kids blasting their boombox at the park.
n. a portable stereo radio. (see also box, thunderbox.) Turn down that damn boom box, or I’ll kick it in.
