swizzling out

What is the last defense of a drowning man ?

So I am in a tight spot - but I just might be able
to swizzle my way out - as for example:

: swizzle ( a b -- a b a b )
                swap dup rot dup -rot ;

I was actually shocked when I wrote this, and
somewhat concerned, but I apparently survived.

Unfortunately there might be a simple forth word
that already does this which I don't know or a
very commonly used way of doing the above
which I don't know

And the prize goes to 2dup - which does the same thing
without all the " hoop la " ..

----- but all that aside,

you can go

swap 'in
and
dup 'in
and
rot 'in
and
dup 'in
and
not rot 'in

all night long ....

rot 'in not and not 'in rot 'in

all night long ( etc, etc ... )

( or even a pie in the face )
now I need sound ... as well ...

but in the end, friend it all ends up to be
just a big mess 'o 2dups .....

( Ooooooohh )
