To totally destroy someone in a fight even though they brought their "friends" to help out.

Guy 2: Yeah man, that one dude was swingin' dick heavy! He totally messed that douche-bag up!
Guy 1: Oh shit, I think I found part of his ear...

Inmate 1: What're you in for?
Inmate 2: Oh you know, I got caught swingin' dick heavy on some guy.
Inmate 1: Don't lie to me. If you were really swingin' dick heavy, you would've destroyed the cops too.
The stage of arousal that occurs between complete limpness and rock hard erection. In this stage, the penis is about half engorged and is too soft to stand proud and erect but to hard to be completely flaccid. The elevated blood levels give the penis a lumbering, heavy feel. Ironically, it is possible to either urinate or ejaculate in this stage (see: messy marvin). Also, because the penis still hangs low, its increased size makes this stage ideal for attempting to visually impress or slapping sexual partners.
When my girlfriend got off the pill I had to start wearin' rubbers again. As soon as I reached for one I went from rock hard to heavy dick.
