Based on full service refueling at gas stations in oregon, where the driver is not allowed to pump his or her own
gas.
In this context here the Oregonian is a full service Blow
Job, where the
woman does all the work from start to finish, from unzipping and de-belting, to cleaning up and re-pantsing.
Can also be called an Oregon Blowjob
Me: Dude, I totally
got An Oregonian right before I
left for work this morning!!!
Dude: NO
WAY!!!
Me: Yeah she kept it off my slacks too!
Dude: That's some quality service there!
