Anal Greenlight 

Through active or passive approval, a partner indicates that further advances toward anal intercourse will not be met with resistance. Active greenlight may come in the form of a verbal agreement that anal sex will ensue such as a vocalized "yes" or, in the case that the receiving party is mute, a nodding of the head. Passive greenlight is more commonly observed and relies of the absence of resistance to anal overtures rather than affirmative verbal confirmation.

After successfully placing two fingers in her anus, Robert knew he had the anal greenlight when Lacey did not protest.

Chinese Greenlight 

It's a variant of the Chinese Stoplight, known by some as the Chinese Firedrill. The difference however is the car does not stop. It takes a whole new level of badassery to accomplish such a task and it should not be attempted by anyone but the most experienced daredevils.

One good strategy for a 3 person Chinese Greenlight is shown below.

Driver: CHINESE GREENLIGHT GO! *climbs out window onto hood*
Passenger 1: You take the wheel! Meet you on the otherside! *climbs out window onto roof*
Passenger 2: *gives wheel to passenger 1, climbs out window into nearby window*
Driver: *Climbs into passenger 1's original seat.*

All: YEA!! We all just gained a badass level!
