Porn star in the mid to late 1970's. Next job was Dean of Students at Notre Dame High School. Walked the halls like a pimp with a big package below. Would adjust himself in public 5 or 6 times per day.
When you shit on your partners back then ride them like a donkey.
In some instances a smear in the hair at the end of the session is acceptable. This is also awarded the desirable name of a hairy duner, or the duner encore.
You give a great duner ! Yeah thanks, I used to do horseback riding .
You look sore today? Yeah I was giving my girl a duner last night till late .
