(alternate spelling of hardon)
1. An erection
2. A problem
Although definition 1 is far more common, 2 is occasionally used. It is used with "for", as in "Having a hard-on for..." It implies an unhealthy fixation, and it is pejorative, in that (obviously) it implies a homoerotic obsession.
Ever since I got Jim fired, he's had a real hard-on for me.

A term used by men over the age of 65, describing an erect penis or choad. One may note that whenever "hard'on" is used, the sentance automatically becomes hilarious, and one must then give these over the hill bed rockers props
