The act in which a male proposes a false agreement with a female, in which the female will perform oral sex on the male and the male promises to return the favour, owing her one in the future, thus the name "68". The male then, subsequently, does not return the favour, thus a scam on the female.
He totally pulled a 68 on her the other night. He hasn't spoken to her since. Word on the street is that she is crushed.
