When someone is high on drugs (heroin) and their head is nodding up and down, like when they are nodding off to sleep and snapping back up
Dude, how much heroin did you do? You keep chucking nods, you're about to fall over.
A random hard on you get during a nod (usually from blues or fetty.)
Bro, wake up! Your Nod Rod is hella noticeable!
Damn, I nodded out on the bus and woke up with a huge nod rod
When you are out in public spaces, (most often your local farmer's market and/or auction, diner, luncheonette, or fire company social quarters) somewhere in south central Pennsylvania, and you notice you are being watched by an old man who does nothing more than give you a barely perceptible nod (perhaps squinting a bit as well), letting you know you are "O.K." and accepted.
"hey man you sure we are gonna be ok walking into this place? It looks rough."
"Yeah man, that old dude gave me the Dutch Nod walking in"
"Really??? That guy gave me the finger!!"
"Well then.... you're fucked"
The small nod of the head by a remote location news reporter just before the speaker begins.
The new reporter, Tim Andrews, gave three news nods before launching in to his report on the storm damage.
When LSD (acid) is combined with an opioid/opiate such as Oxycodone or Hydromorphone. Users experience classic psychedelic effects and visuals while being in a more mellow, and euphoric mental state. Often used to lower anxiety from psychedelics without reducing visual effects in the way benzodiazepines or alcohol would.
LSD is sometimes substituted with Magic Mushrooms for this combination.
Sarah had a great time Nod Flipping last weekend! Usually she freaks out on LSD, but she seemed much more relaxed and happy when she took a low dose of Oxycodone as she was coming up on the acid.
The Detroit nod is often seen in "the trenches" and more violent streets of Detroit. With Detroit being one of the murder capitals of America, any social interaction must be handled carefully. The "Detroit Nod" is a social gurantee that there are no problems and no worries. Essientially; I won't hurt you, you won't hurt me.
In Detroit: "Cuz gave me the nod so I knew he was straight"
"Why that dude nod at people like that?"
"That's the Detroit nod bro!"
