Whenever a girl and a guy are fooling around and things get very hot but all of the sudden she stops foreplay and does not allow penetration. Obviously the guy stops after her "Thou shall not pass!"
"Man I am really in need of having sex with her"
"Did you not have sex with her yesterday?"
"No, she Pulled-a-Gandalf"
"Did you not have sex with her yesterday?"
"No, she Pulled-a-Gandalf"
