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.

Get the Flicker-Knicker or Flicka-a-nikamug. A Greek name that means "God" or "Goddess". They are one true brilliant mind. Not a very common name so, not a very common person. They're different, but in a unique way. They support the LGBTQ but are not in it. They are very easy to trust and is there for their people. They are very enthusiastic and has great style! You are very lucky if you have met a Nikas.

Get the Nika Marin Pereiramug. Nika is a girl with brown eyes and tan skin. She is a Persian girl who has strict parents that care a lot about her grades. She has about 10000 million cousins that she can't keep track of and meets a new family member every day. She hides a lot of things like anxiety, depressions etc. But she puts on a smile whenever around other people. She studies her butt off to get perfect grades for her parents all while doing sports, extracurriculars, and living a normal life. She doesn't let too many people get close to her because of how many of them have hurt her in the past, but once you get to know her you'll see she is an amazing friend. Never ever lose a Nika, because they might be the best thing that ever happened to you.
My friend's name is Nika.

Get the Nikamug. Sheś the smartest of class/work and sort of shy. She is as equally pretty on the outside as she is on the inside and is optomistic.
That girl is so Nika
