No - you can only use an ess-set when the two s’s belong to the same syllable.
But you are correct - I spelled it wrong.
Who would have thunk it.
“augendes” +”sammen” = “ss”
Also, “ausstossendes” requires the “n” - infinitive verb +”des” becomes an adjective.
And, “stossen aus” is a seperable verb, “to burp”. So you need “ss” there, too.
;)
I considered sprinkling in rändom umlauts to fürther the joke...
