Military term used to describe any man able to walk. If you were walking your dick was swinging hence the correlation. Particularly remembered from the American/Vietnam conflict.
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.
Freeballin. When a guy goes without underwear in shorts that show his vpl (visible penis line) or his dick is visibly flopping around. It's especially common among jocks at the gym, or when playing basketball or volleyball.
There's a little girl in our neighborhood
Her name is Charlotte Johnson and she's really looking good
I had to go and see her
So I called her on the phone
I walked over to her house and this was going on
Her brother was on the sofa
Eating chocolate pie
Her momma was in the kitchen cutting chicken up to fry
Her daddy was in the backyard
Rolling up a garden hose
I was on the porch with Charlotte feeling love down to my toes
And they were swinging (swinging)
Yes they were swinging (swinging)
Little Charlotte she's as pretty as the angels when they sing
I can't believe I'm out here on the front porch in this swing
Just a-swinging (swinging)
Yeah we'll be swinging (swinging)
Yes we'll be swingin’ (swinging)
Little Charlotte she's as pretty as the angels when they sing
I can't believe I'm out here on the front porch in this swing
Just a-swinging (swinging)
Now Charlotte's she's a darling she's the apple of my eye
And when I'm on the swing with her it she makes me almost high
And Charlotte is my lover
And she has been since the spring
I just can't believe it started on her front porch in this swing
A-just a swinging (swinging)
A-just a swinging (swinging)
Little Charlotte she's as pretty as the angels when they sing
I can't believe I'm out here on the front porch in this swing
Just a-swinging (swinging)
I said little Charlotte she's as pretty as the angels when they sing
I can't believe I'm out here on the front porch in this swing
Just a-swinging (swinging)
