Where does tweak come from?
The verb tweak has many non-slang uses in English, including “to make usually small adjustments in or to” and “to injure slightly” (as in “tweaked my knee”). Its oldest sense, from around the turn of the 17th century, is “to pinch and pull with a sudden jerk or twist,” as in “I tweaked a bud from the stem.”
It is perhaps this sense of tweak that led, in the early 1980s, to a slang sense for the erratic behavior and sometimes twitchy/jerky body movements of someone under the influence of methamphetamine or another stimulant.

—Lauren Greenfield, The New Yorker, 24 Mar. 1997
Noun uses of tweak to refer to methamphetamine as well as crack cocaine also arose in the 1980s, and tweaker first appeared in 1980 for someone who uses meth and especially crystal meth.
Figurative use of the drug-related tweak/tweak out also arose in the 1980s.
“I’d better get going. The Wangsleys will be tweaking out if I’m late. See you at school tomorrow."
—Barthe DeClements and Christopher Greimes, Double Trouble, 1987
This use of tweak has recently become popular on social media after American rapper Lil Nas X’s comment, “nah he tweakin,” about Tony Hawk, went viral in 2021.
Vast numbers of people on Instagram are using the phrase “nah he tweakin”, and it is all the fault of skateboarder Tony Hawk’s blood. The phrase has gone viral on the app to the extent that it has even been used by Instagram itself. And it all began with a strange feud between singer Lil Nas X and Hawk, over the use of blood in products.

How is tweak used?
Somewhat synonymously with freak, stress, and crash out. Tweak out can also be used as a noun to refer to a specific instance of getting extremely excited, irrational, or distressed over something.
