This Universal Sign!

"You know you are about to get some good head when she put her hair in a ponytail!" 

Well, well, well, as a man, this is when you realize you are about to have the good time you are hoping for all the day! Take this ponytail thing as a sign. If your girl gives head with her hair still hanging loose, she probably does that out of compulsion. If she looks like this girl in the meme, boy, she is all set to blow your mind, or whatever she is supposed to blow!
