Repeatedly and obsessively engaging in a SIMPLE behavior or motion, like pulling at one's face to remove imagined objects that aren't there. Persons addicted to methamphetamine will engage in this type of compulsion. Yet, it is a myth some people subscribe to , that the behavior can extend to having sex. People high on meth can't perform anything NEARLY that complicated when they're tweaking, let alone maintain an erection or climax.
When your up for days cuz your unable to stop drawing and reading so the pictures and posters start winking at you, making facial expressions, and appear to be breathing
“The poster just winked at me, im tweaking.”
“I need sleep but my brain won’t stop tweaking.”
When someone bends over - arches their butt - and wiggles it - usually done to trap, techno, or rap music. This dance has exploded in popularity partially because of celebrities, it is now a global phenomenon.
John: "Dude do you like watch twerking videos on youtube and stuff?"
Keith: No John, I act like a civil human being and use newtwerk.net instead!"
Someone who is so high on methamphetamines,tweekin' that you can tell that they are from a long distance. Like a ray of light from a beacon. Flailed out so bad that small children ask their parents "Whats wrong with that man/women?"
Oh my god look at that chick with the scabs on her face having her shopping cart flipped on it's side trying to fix the wheel. I can tell she's so spun cuz she's a tweekin beacon.
