DNeff 

the perfect bestfriend for a girl to have, who isn't gay. He's funny, strange (in a good way), huggable, and looks mighty fine in skinny jeans and tie dye shirts. DNeff is the best guy to smoke up with, and is always down for some hugs!

musical attention defficit disorder

People with a musical attention defficit disorder have a tendency to switch every (or almost every) song they listen to midway through (if not before that).

Also abreviated to M.A.D.D.

I'd swear that John has a Musical Attention Defficit Disorder. When I was listening to his MP3 with him earlier, he couldn't stop song skipping! It drove me nuts!

deffynition 

The definition a person defaults to that is more so a take or spin on the official written word which tends to add flavour and/or character to said 'defined' word's understanding for people locally involved.

"Carol's deffynition on the matter is not the same as yours. Her upbringing and use of Internet memology has caused her to have a slightly different opinion on what you think the definition actually is for the rest of us *here*."

"Kevin's deffynition of sperg not only implies that a person might have Asperger's but also includes the idea of *them* usually trolling streamers on Twitch in a way that garners a streamer's attention, in a spastic sort of sense."

"Urbandictionary.com is at the core of the Internet's play of deffynitions. It's better understood nowadays that there is not only one given definition for everyone and everything at all times."

Deffie

When weed is vapourised and smoked through a bottle of water. It is prepared by making a small hole in a 2 litre bottle of water with a tin foil lid in which the weed is held in. The hole lets water out which fills the bottle with smoke. You then block the hole and remove the tin foil lid. Give a nice shake and inhale :)

Yes lad what you saying, going for a fat deffie at vic park g
