when you see a girl in the distance that looks good and she gets closer you realize she is unattractive your face looks like you have alot of lemon heads in your mouth.
did you see mike at the bar the other day he was with a total Lemon Head
Jane: "Man that lemon head tasted so fucking good last night!"
Julia: "Omfgyeah, the best kind of lemon head is the mongolian type... I love Mongolian BBQ."
