Description: Stand at the urinals and make eye contact with the person next to you. If they seem interested, motion them to an unoccupied stall - the handicapped stall is best. It's big enough, and the walls are tall enough for you to stay hidden. Keep it discreet, though.
Alternately, you can go into a stall and wait for someone to enter in one of the stalls next to you. Tap your foot under the divider to see if they are interested.
