Is split tail still used informally?

Similar to swinging dick for guys. I haven’t heard split tail used for ladies in quite awhile. Often abbreviated as tail.

Is it still commonly used?

You could ask the next BAM you see.

Broad-Assed Marine. My former Navy-lifer BIL advised me never, ever, ever to say that within earshot of a split-tail Marine.

I haven’t heard it in years.

Along with RCH and 4F

BAM is a new one for me.

shavetail is another good one. Don’t think it’s gender specific. A 2nd lieutenant.

My elderly father uses it sometimes. Don’t know where he picked it up, he was never a marine.

There was an old joke among the construction types:

Kid has been watching a construction site down the street. His father asks him to help him build a doghouse.

Father: “Is this stud straight?”
Kid: “Move it to the right a cunt hair.”
Father: “WHAT?!”
Kid: “Ah fuck it; nail it.”

People often say move it to the right a hair. Or shorten that 2x4 a hair. I often wonder how many of the younger guys knows it has been abbreviated.

I often give measurements that way for cutting lumber. 3 ft 7 inches and a hair. Meaning make it a 1/16 extra. Or 3 ft 7 inches minus a hair. meaning just under that measurement.

Me, I prefer measurements to be a bit over, a bit extra. So, five inches and a cat. Four-foot seven and a cat. Nineteen yards and a cat.

(I have an add-a-puss complex.)

My granddad said “Ah, another split tail” when my sister had her 3rd girl.

I’ve never come across that expression in my life.

I’ve seen “split tail” in various books but I’ve never heard anyone say it out loud.

Wow, that’s a pretty gross phrase.

I’ve 55 and have been in a lot of man talk conversations, and I have never heard that phrase used before.

I’ve heard the term maybe twice, one time being in the lewd graphic novel “The Pro” by Garth Ennis. Don’t recall the other time exactly.

I’m 43.

Heard them all more or less. As to them being good or bad, depends on the location, context, person saying it & how they do.

But I have been in some interesting places during my interesting life. IMO.

I have heard that, and worse, but not generally in polite conversation.

Then you’ll love knowing why women have legs.

So they won’t leave a slime trail.

I’ve heard it more from military friends, but less frequently in the past decade.

Heard it, used it. Not very often for either, though.

I’ve only seen it used in books, and the circumstances weren’t exactly “informal” but generally only conversations between foul-mouthed military men of some sort. It’s a crude insulting word, I certainly HOPE it doesn’t get used in informal settings.
