The phrase used when you hookup with a rather unattractive girl only for a blowjob. If this line is used you cannot hate on your friend for getting with her and the subject must be dropped immediately.
Guy 1: Yo that girl ugly as hell why you get with her for!?
Guy 2: Bro, I did it for the neck.
Guy 1: Oh ok its all good then.
