half a hard on

1) self explanatory- a half hard penis. 2)a dummy, a half wit, can't think clearly

1)I got so drunk I couldn't play "hot dogs and doughnuts"with my girl with a half a hard on. 2)that half a hard on is still paying into social security.

Bridget: "Wow, last night was bad."
Muhammad: "What do you mean? I had a great time!"
Bridget: "Yeah but you were a little hard on the beaver last night..."
