Loansome

Nuncle: ’Tis none so mincey as a Farrington chop
And nowt so loansome as a fixed rate swap.

Büchstein, Die Schweizer Heulsuse

Loansome
/ˈləʊnsəm/ (adj.)
Having the characteristics of a loan. Thus, unhip: fusty; old-fashioned. Luddite. Stone-age.

There is some irony in Nuncle’s wry remark, because while achingly cool and edgy swaps are, of course, powered by loans. But only a boffin would say this in polite company.

Compare: Swappish.

Origin: archaic, possibly coined by Otto Büchstein, in Die Schweizer Heulsuse.
