Fluxing 

From the verb 'to flux'. In the Robert Zemekis saga 'Back to the future', inside of the time traveling Delonean is localized the Flux Capacitor, which job is to Flux. So the Delonean needs the Flux Capacitor to keep Fluxing for time travel being possible.

Marty McFly (checking the Delonean before the time travel)(first movie): Flux Capacitor, Fluxing.

Flexing 

The act of bragging about money-related things, such as about how much money you have, or about expensive possessions like designer clothing. Often done by young kids and DoucheTubers.

I hate this YouTuber, because all he does is just keep flexing on his fans and then call it “comedy”.
