For real this instantly weeds out any squares (lol squares who even still talk like that I'm so stoned) and as a bonus when you find others like yourself you got a bond now.
That's literally how I met one of my best mates. They had a box of dihydrocodeine out and I kept glancing because it's an odd thing to just have one on you... I know that because I do it too so I mentioned it "Paramol eh? Gonna CWE those?"
Then I brought out my bottle of lean and we just had a great fuckin time chatting and getting high (hey it's a bar, gotta take psychoactive substances.)
Then this guy who was sitting close enough to hear what we talked about informed us he's a doctor and drugs are bad, m'kay. I said well mostly we're talking about the same drugs you quacks prescribe every day.
