Pricklouse ‘tailor.’ From the OED:
pricklouse (‘prIklaUs). Now dial. Also [19th century] prick-the(-a)-louse. A derisive name for a tailor.
1500-20 Dunbar Poems xxvii. 5 Betuix a tel3our and ane sowtar, A pricklouss and ane hobbell clowttar [telyour 'tailor'; souter 'shoemaker, cobbler'; hobble 'cobble, mend (shoes) roughly'; clooter 'patcher, cobbler']. 1668 R. L’Estrange The Visions of Don Francisco Quevedo Villegas (1708) 151 The poor Prick-Lice were damn’dly startled at that, for fear they should not get in. 1709 O. Dykes Eng.

A. 1796 Burns Answ. to Tailor ii, Gae mind your seam, ye prick-the-louse, An’ jag-the-flae. [jag 'prick, pierce' (hence the nickname "the Jags" for the Partick Thistles, a Glasgow football team familiar to fans of the wonderful Jack Laidlaw detective novels of William McIlvanney); flae 'flea' (ie, "jag-the-flae" is modeled on the traditional "prick-(the-)louse")]
Since the first quotation is from William Dunbar, let me here put in a plug for him as one of the great early modern poets; he wrote in Scots rather than southron English, but it’s worth making the effort for such a brilliant poem as Lament for the Makars (“maker” was the traditional Scots term for ‘poet’), with its refrain “Timor mortis conturbat me” (‘The fear of death disturbs me’). And from this brief biography we learn that he
has the curious distinction of having been responsible for the first printed use of the word “fuck” (1508), thus establishing a long and noble tradition of which some critics of Kelman or Welsh appear to be quite unaware….
“The Flyting” is a verse-quarrel with the poet Walter Kennedy, and contains such choice insults as “wan fukkit funling” and “cuntbitten crawdon”. Perhaps it was language such as this which had something to do with Scotland becoming the first country to try and make swearing illegal (1551). We might add as a parenthesis that the later English puritans, undeterred by the complete failure of the Scottish law, followed suit by making swearing at one’s parents a capital offence (1649). Much later, Mussolini put notices up saying “For Italy’s honour, do not swear”, but look where it got him. Before leaving this interesting topic, it should be added that the powerful word which Dunbar put into print in 1508 was not decriminalised until 1960, only appearing in dictionaries after 1965, but by 1982 it was thought necessary to declare “fuck” unparliamentary language. Nevertheless, a hundred years earlier it had already showed up unexpectedly in “The Times” of all places, probably due to a mischievous compositor, in a Parliamentary report which stated: “The Speaker then said he felt inclined for a bit of fucking.”
