A BOLO
A bolo is what the cops say when they're trying to catch someone. It's like a shout-out to the whole city: 'Hey, look out, we're coming for you.'
'The cops just said 'bolo' on the radio. Someone's in trouble.'
'They're looking for the guy who stole the pizza truck. It's a bolo.'
'The cop said 'bolo' and I ran.'
