Green Stop Sign
Mixed signals, most commonly coming from the fairer sex.
We were in the club and she was dressed pretty slutty and dancing pretty dirty, but kept pushing me away. She really threw up the ol' green stop sign for me.
Green Sign
When you con someone into signing a deal that benefits you better than the other member.
“Err.. Joe? It says you get 99% of my company for Nothing... Are you trying to get a Green Sign?”
“No, no. Read less, sign more.”
“No, no. Read less, sign more.”
