Grandparent Joint 

Save the roaches from your joints and combine the resonated pot into a new (more potent) joint. If planned correctly, this technique can be repeated endlessly, producing high-potency grandparent joints and even great-grandparent joints.

"Looks like we've got enough here for a Grandparent joint, anyone down?"

"I have been saving the great-grandparent joint of last summer for my backpacking trip."

jailhouse joint 

a really thin marijuana cigarette sometimes cut with tobacco. if an inmate smuggles some pot in the jail, he/she rolls it into a jailhouse joint and everyone who wants to smoke it with the inmate has sex with each other (including the owner of the joint). The ones in prisons can be huge, but in the county jail they're thin, hence the name. On the Outside, sex isn't necessary to smoke one.

dude: this aint no nick bag! I got ripped off! It's only half a nick!

buddy: at least you can roll a jailhouse joint outta it.

Geometric Joint 

A joint rolled with detailed and synergistic reliance on fractal geometry and LaGrange multipliers. Also known as "fractal joint."

One end of the joint is (theoretically) infinitely large and the other end (theoretically) achieves nothingness through complex geometrical scaling equations that are too long for me to go into right now.
Volume of marijuana vis a vis length should probably not exceed 7 m/s^2, but whatever, you know, play it by ear. Must have at least one corner.

Hells ya yo i just talked to miles he's planning a fuckin geometric joint its gonna be legit as balls

Blood Joint 

A collection of marihuana thats consits of one's own personal stash, and is obtained from a source of known violence, much like a blood diamond. This phrase can only be used within unison of a joint styled form of smoking.

Much more vague varieties can be used for same effect: blood pot, blood tree, blood choad, blood blunt, etc, ...

Harmonica joint 

A certain of joint-rolling called a "flaming backflip" (you can look this up anywhere) cuts a hole along the paper, so you must inhale through the hole instead of through the roach. The result looks as though the smoker is playing a harmonica

try to roll a flaming backflip. it will probably turn into a harmonica joint. you tube the flaming backflip.
