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.
My mistress was on her period so she gave me a blowey.
