when one is under the influence of mdma or simular, simular to gurning however its the unstopable repetative action as if you're chewing something, resulting in a sort of annoying clicking noise. large use of the tongue.
oi steve! you're jerbing like a cunt and it's pissing me off!
The process of extration, commenly used for extracting codeine from other painkillers (paracetamol, ibuprofen) it is usually combined with in legally avaliable pills. it is a fairly simple process however time consuming but necassary to get the nice codeine. i will go into detail but read no further if you've ever recreationally taken any other opiates (morphine, heroin) as codeine is a weak form and won't give you a buzz you'll OD before you get 'there'.
first get yourself some codeine and paracetamol tablets (co-codamol) then boil some water. depending on the strength of the tablets you want to empty around 300mg of codine so calculate howmany pills you need. then pour boiling water over the pills mix them into the water, then allow to cool, preferably in a fridge then filter the water using coffee filters, the liquid left will be diluted coedine without binders or paracetamol. result
'argh mate cold water extraction is effort, but its worth it'
'nah man since i had those morphine based pills codeine just don't work'
