HDD stands for Holding Dick Disorder -- a particularly crippling and unpleasant psychological handicap demonstrated by a large number of unsophisticated, misogynistic, insecure and pushy members of society who have been brought up to revere excessively controlling and insecure male figures as primary role models in their early development/environment. Usually translated as machismo, the basic symptoms of HDD are as follows:

-the inability to separate one's brain from one's genitalia
-the propensity to perceive a concession of something(i.e. conceding a point, acquiescing an idea, agreeing to a compromise, admitting fault or wrongdoing, etc) as a direct threat to one's masculinity
-Frequent show off behavior, bragging, and need to prove oneself to one's peers (result of insecurity)
-Extreme confrontational behavior, low threat threshold, and especially in the presence of other male individuals
-Extreme homophobia, frequent homosexual jokes, usually resulting from super-closeted homosexual tendencies that are improperly dealt with in psychosexual development
-Frequent inability to reach agreements with people, notorious inflexibility in interpersonal relationships due to a need to control, lack of self knowledge, etc.
-generally described as "asshole"

People with HDD may be male or female, but the most frequent victims are male and of low-class backgrounds. The best remedy for HDD is a giant kick in the nuts.

Heroin Dope Dick. When you finally give it to a girl, break her in and get her hooked. That point when no matter the time of the day, no matter the place, she is down to get it. May cause her to show clinger symptoms and eventually lead to psycho behavior. use with caution because once they're on it, its hard to get them off.
Adam: So how was your night with Lisa last night
Sean: you already know, I gave her that HDD and now she won't stop blowing up my phone.
Adam: you know what they say, once you give her the HDD you either get her off or you get her off of it.
