Swingin' Dick Heavy

The action of seriously owning an individual.

To totally destroy someone in a fight even though they brought their "friends" to help out.
To go about your business of kickin' ass and takin' names without even caring.

Guy 1: Holy crap! Did you just see that fight?!
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.

Swingin' Dick

Refers literally to a man, but specifically to someone whose skills or physical stature make him especially intimidating. A badass. Can be used metaphorically to refer to a woman, as long as she is a total badass at something.

There is a common misconception that this term refers to any male because it references the male organ, but the more important part of the term is "swingin'." That is, not just any man, but an especially potent or imposing man. Hence, a badass.

1) As in No Country for Old Men: "Call my room if anybody comes in--and by 'anybody' I mean any swingin' dick."

2) A: "Did you read that new Judith Butler article? She totally destabilizes the regime's reinscription of normative typologies."

B: "Yeah, she's a swingin' dick when it comes to critique. Also, stop talking like a d-bag."
