bush patrol
Kissing and caressing. I heard you were on bush patrol with Andrea last night—did it lead to anything more?
on patrol
In the process of moving around some area in order to observe, inspect, or protect it. There are only two guards on patrol, so there should be plenty of opportunities to slip in undetected. Officers Smith and McCluskey, you'll be on patrol in the east district tonight.
(out) on patrol
away from a central location, watching over a distant or assigned area. (Said especially of police and soldiers.) Officer Smith is out on patrol and cannot see you now. The soldiers who are on patrol on this snowy night must be very cold.
bush patrol
1. n. a session of necking and petting. (Here patrol has the military meaning of assignment.) Martha and Paul spent the evening on bush patrol.
2. n. an imaginary search through campus shrubbery to flush out the necking couples. Bush patrol starts at midnight, so be in by then.
