In the automotive industry, upbadging is when you are driving a lower-trim or entry level trim version of a specific vehicle and you decide to add custom badges, decals, and/or logos from a higher trim in order to make your vehicle look faster/more powerful/more expensive than it actually is.
For example: adding Hellcat badges to an SXT Dodge Challenger is indeed upbadging, and definitely the most godawful of them all. This is because a Hellcat V8 can put out 707hp while a V6 SXT only has 305hp. You drive an upbadged SXT and try to race an actual Hellcat, you're gonna look stupid and you're gonna get called out. Don't do it. Either be proud of your ride or save up for the real deal.
Wow, Liz must be unaddictable now. Her favorite fish died, her car broke down, and she's quarantined in her house with those crazy kids, but she STILL hasn't relapsed!
A corruption of 'up and down' suggesting a frenzied running from pillar to post in desperation; especially when in trouble or trying to curry favour with personalities to influence circumstances or gain preferential support. (Nigerian origin.)
