A what? Or is it a which? Or perhaps a twitch? Maybe it’s the rhymer for the word “week” when you are babbling rhymes. I managed to get three definitions from various online dictionaries:
(1) FLEEK: flēk/ adjective INFORMAL in the USA
Why do you need the “on”? How come this a word requires a proposition or possibly, a preposition? Who made up that rule?
(2) From the “Urban” or perhaps “Urbane” Dictionary:
A shitty word made by shitty people with no fucking lives.
Dumbass: “My eyebrows are on fleek!”
Me: “Who the fuck cares?” — by wastetimechasingmemes
(3) On Fleek: Born (or maybe it just floated in from another reality) in a Vine video on June 21, 2014, the term fleek is a busy word. It was originally (and still is most commonly) applied to perfectly-groomed eyebrows, but the word has been used to describe everything from hash browns to skateboards.
(4) Fleek or “on fleek“: A word used by people whose intent is set on decimating the English language, thus further depleting the ever-dwindling repository of individuals capable of intelligent conversation.
(5) Wiktionary – On fleek – Adjective. on fleek (comparative more on fleek, superlative most on fleek) (slang, of eyebrows or hair) Sleek and perfectly groomed or styled. quotations; (slang, of an article of clothing or outfit) Stylish and perfectly chosen or put together.
The next time I have my eyebrows waxed, I know the precise word to use. My Vietnamese eyebrow waxer doesn’t understand even basic English so this will be as meaningless to her as it is to me.
