When a chick is giving you head, you gag her so hard that she throws up, and you use the vomit as lubrication to have sex with her.
Paul took his coworker out for drinks one night. Before long, she was drunk & she started giving him head. He was too much for her to handle so she threw up on him, and as payback, he gave her the Dirty Toos.
