dirty Gannon

The act of finding any virgin, usually a young girl, wearing a skirt, reaching under it, and touching her, leaving her following the man home and begging him for more.

The man across from me on the subway pulled a dirty Gannon, and now that teenage girl is on her knees begging him to take her.

dirty Briley

When a man seduces his own daughter and takes her virginity in front of his jealous wife, causing her to kill herself, and the man dates his daughter.

Wow, he and his daughter look so much like a couple ever since his wife died, I bet he pulled a dirty Briley on her.
