n. The act of a sober male taking advantage of a female while she is absolutely trashed.
The term originated Valentines Day 2009 when a guy named McCracken saw this totally wasted girl and, at that moment, he decided to seduce and eventually have sex with her because he wouldn't have any chance with doing so if she was sober.
Society tends to frown upon these people and their actions.
