A phrase used to not-so-discretely describe oral sex on a male.
(phone conversation)
guy1: Hey man, what are you up to right now?
guy2: Um, right now? Well, my girlfriend is traveling south on shaft highway.
guy1: Oh shit sorry dude! Later!

(two girls talking about the night before)
girl1: ... then I took him out to my car and I traveled south on shaft highway.
girl2: Did you go all the way down to the cul de sack? LOL!
