RIPPED vs JACKED
Is ripped good, and jacked bad? It seems you can use both of these words to say that for example you have a proclivity for visible ab muscles, but if you're jacked up then... you're in bad shape.
I've seen multiple forms of these words and combinations used in movies recently, as to denote both being gravely injured and/or looking good, so I figured I'd get to the root of it all here. Quick Google...
Ripped, definition #3 (of 3):
Having well-defined or well-developed muscles; muscular.
Jacked, definition #2 (of 2):
(Of a person) having very well-developed muscles.
The source here being Oxford Languages. Merriam-Webster has similar definitions for both.
Jacked up, on the other hand, traces back to the primary definition for jacked, of being physically or mentally stimulated from the effects of a drug or stimulant. (Oxford Languages)
It's not official, but in common slang it thus means: Wrecked, messed up.
As you would be were you under the influence of drugs as they were said to influence you with continued usage.
There's no similar slang for ripped up, though literally it means the same.
So there. Words: jacket of all trades.
