When a male enters his member into a womans chatter box. The difference between this and a regular blow job is simple. Its just better. The term originated while a group of people were watching A Walk to Remember. All everyone wanted was for Mandy Moore to give the poor guy a blowey. So cheers to you guy who didnt get a blowey, you stayed strong and probably banged her behind the scenes.
A "Power Blowey" is a blowjob that is done fast and efficiently. It is similar to a "quickie". No extra cute stuff. Just straight to the point and finish line as quick as possible.
We didnt have time for sex because we had to meet our friends for breakfast, so she just gave me a quick "Power Blowey" for now.
