Final word
So, to summarise the slang word “flex” comes from the African American Vernacular English (AAVE). The word is derived from the literal act of flexing one’s muscles to show them off, and to better boast about them. The word later came to be used metaphorically, expanding its meaning to include boasting and bragging about other things besides physical prowess.
In the 2000s and more so later in the 2010s and more recently, social media apps provided entire new platforms on which to flex. Whether it’s flexing your skills, abilities and certificates on LinkedIn, or showing off your beauty routine on Instagram, or boasting about your weight loss journey or bulking up journey, the internet has made flexing easier for everybody. Even to the point where the flexing of some would make the many feel uncomfortable or inadequate.
Flexing can be a good thing when you are proud of your accomplishments, but sometimes it can easily be taken the wrong way, and not go well for you. People are generally happy to back you, but are less so when they are struggling themselves.
