lemonfinger 

When one picks one's rectum and then takes the finger to someone's nose and asks: "Do you smell lemon?"

Bob: "Hey, did you ever lemonfinger anyone in school?"
Gary: "Yeah, I did it to my shop class teacher!"
Connie: "Dear bin Laden, please take me now..."

Lemon Finger 

When Don Lemon shoves his hand down his pants swirls his fingers around his junk and then wipes it on your mustache

Damn man quit touching your balls and wiping it in my face, you have a lemon finger!
