Anglo-American term for a “wedgie” or “snuggy,” a word that was frequently used in the US in the 1970's and 1980’s to describe what happens when your undergarments make their way (
intentionally or not) up into the crack of your buttocks. The term is derived from the act of flicking one’s knickers--the
British word for women’s panties (i.e. long bloomers formerly worn as
underwear by women and girls).
I hate wearing this polyester thong because it has given me a chronic case of flik-a-knicker—not too mention a raging case of jock-itch.
Byron’s incessant attempts at giving
Gertrude a flicka-nicka were mildly amusing, but
eventually became deeply boorish,
particularly after he managed to tear the poor woman’s panties.
