Etymological notes
Contrary to the widespread belief of this being a euphemism, it arose as a pronunciation spelling (of the older form arse still used in the UK, Australia, New Zealand, etc.) that shows the assimilation of /ɹ/ before coronal consonants (especially /s/), a phenomenon that has been present in nonstandard speech from the Middle English period onwards; this is distinct from the later phenomenon of non-rhoticity as /ɹ/ was lost before it could modify the preceding vowel. Other instances of this phenomenon (some of which retained both spellings with different meanings) include cuss from curse, gash from garsh, bass (“fish”) from barse, bust from burst, passel from parcel; see :Category:English terms with assimilation of historic /ɹ/ for a more extensive list.

Borrowed from Polari, from Italian parlare (“to talk”). The loss of the first r and the changing vowel quality of the non-stressed vowels is due to the non-rhotic UK accent which reinterpreted the phonemes.
