In British English slang, "sket" means "promiscuous woman". Apparently that's from Caribbean slang "skettle", for which I can't find an origin.Sketna means Filthy
where the last meaning might have had a vovel shift to 'sket' once the humorists took over 'skit'.'skit' as "piece of light satire or caricature," 1820, from earlier sense "a satirical remark or reflection" (1727), originally (1570s) "a vain, frivolous, or wanton girl" (originally Scottish, now archaic), related to verb meaning "to shy or be skittish, caper, frolic" (1610s), perhaps from Old Norse skjuta "to shoot, move quickly"
