flash around
To show or reveal something, often in a quick gesture. A noun or pronoun can be used between "flash" and "around." Oh yeah, Katie's been flashing around her engagement ring constantly since Tom proposed—it's so annoying.
flash something around
to display something so everyone can see it. (Usually something one would hold in one's hand.) Don't flash your money around on the streets. She flashed around the pictures of her grandchildren every chance she got.
