to attract negative attention to yourself, esp. attention of the police.
You're hot boxin selling that shit on the busiest corner in the city.
When you and your partner have sex in a car, the windows fog up. this is hot boxin. Or when you and your friends light up a joint
and the smoke clings to the windows.
