My dad proudly flew one that said FORTH <3 IF HONK THEN. Yes, people did honk.

Prediction: someone will make a reverse polish notation skill for interacting with claude claiming all sorts of things, like caveman, turn into another markdown as a service company, and make the news.
See Self's "dynamic deoptimization", where it constructs a virtual return stack on demand that you would have had, were it not for the JIT compiler's agressive inlining.

is it me or is forth coming up a lot lately? or am i just having a plate-o-shrimp situation?

FYI: Forth can be very readable!
IT DOES NOT NEED TO BR ALL IN ONE LINE
Most commercial forth source code is totally readable and maintainable:
comments, newlines, macros, high level commands etc
It's a total myth that its 'write only'. The same nonsense is spreaded by some nerds who actaully never wrote a single program in it.
ps. same goes to COBOL. 99% of fud by guys who never even wrote a simple program in it.

Saw the same joke with Postscript many years ago.

A different way to say the same: in forth, words get pushed on the stack, and popped from the stack by words that take arguments:
code stack
I Forth love
Forth love I
love I
Forth
; love presumably pops
; subject, object args
; from stack - and does something
; perhaps prints as side effect

Here is some inexplicably but meticulously formatted FORTH code that uses right justified indentation! Including reverse polish notation assembley.
( FMOVE -- functional intersegment move ) HEX
88 CONSTANT *MOV* ( fn = 0 ) 20 CONSTANT *AND* ( fn = 1 )
08 CONSTANT *OR* ( fn = 2 ) 30 CONSTANT *XOR* ( fn = 3 )
CODE FMOVE ( fn s.seg s.off d.seg d.off length --) AX, SI MOV
CX POP DI POP ES POP SI POP DS POP DX POP AX PUSH
AL, # *XOR* MOV DX, # 3 CMP 1$ JE
AL, # *OR* MOV DX, # 2 CMP 1$ JE
AL, # *AND* MOV DX, # 1 CMP 1$ JE
AL, # *MOV* MOV 1$:
CS: HERE 5 + , AL MOV ( modify "[DI], AL MOV" ) 2$:
LODS ES: [DI], AL MOV DI INC 2$ LOOP
AX, CS MOV ES, AX MOV DS, AX MOV SI POP NEXT, END-CODE

Forth I assume uses reverse polish notation: arguments before the operator.
3 4 +
for example, would return 7.
zabzonk 6 hours ago [-]
> would return 7
more pedantically, it would push 7 onto the stack
dbcurtis 4 hours ago [-]
even more pedantically, would remove 3 and 4 from the stack before pushing 7
DonHopkins 4 hours ago [-]
Even oddly more pedantically, that's the operand stack, not to be confused with the separate return stack. >R and R> move values between the two stacks.
On the other hand, PostScript also has a dictionary stack, which you can use to implement a Smalltalk-like object oriented programming system. And its data types and executable code are basically polymorphic homoiconic JSON (like Lisp), not raw untyped bytes like FORTH.

That is, you provide the data first (I and Forth) and the command (heart) last.
But then he would also say: Forth is the path to the Light Side…
