The act of dedicating a significant amount of time convincing a girl to come back to your room to hook up, but vomiting onto her moments before it happens. Rather than fuck, the night ends with the girl taking care of your drunk ass.
'I accidentally gave that girl a thanjob last night rather than hook up with her. Obviously, I had to murder her so that no one would know.'
