When you have the Spliff, and have had your tokes on it, go to pass it to the person who is next, and when they go to reach for it take another drag fast and THEN pass them the spliff. this is known as being Snaked.
G-roc goes to hand the spliff to Konky, Konky goes to take it, G-roc takes a fasst drag before he can take the spliff.
The other people that have just wittnesed the Snake then proceed to say something along the lines of :
"Ohhhhh shiiiiiit man!!!!! you got SNAKED!!!!"
this is then followed by some laughter.
2. Yea I was making out with this girl for almost an hour and finally I snaked her...and she loved it
Translated - "I Say, Samuel. You really should have seen the lovely fair lady i embraced in a kiss with only but an evening ago. She wished to retire to my humble abode to make passionate love, but unfortunately her monthly period was in full flow. However, count it as most certain; next time we meet she will, without a doubt, be getting SNAKED"
"So where are you staying once we arrive in Florida? Ever been SNAKED on a plane?"
Much like a plumber "snakes" a drain.
