jimble jam

Specific terminology for a rock climbing move, which may be useful when crack climbing, particularly overhanging jamming cracks. Only achieveable by males. Employed when one needs to rest both arms and both legs at the same time. Involves inserting one's jimbler into said crack and enlarging it until it jams in nicely (similar to a fist jam), thus enabling the climber to shake out all four limbs and generally take a good breather. Requires a first-rate imagination in order to maintain the hold - thinking about accounting or thermodynamics may *actually* result in injury or death.

He would never have flashed the route if he hadn't pulled out that amazing jimble jam under the roof. We were lucky our view was obscured.

clam jam

The female equivalent of the cock block, but amongst two girls who'd like to get it on. A much more graphic term to use than box lock.

Trent is hanging out with a bunch of his lesbian friends at a bar. One of his friends' name is Lily.

Lily: That girl at the bar is so hot. I'm going to go hit on her.
Trent: No, I'm cranky. Let's go home.
Lily: Ok fine.

Trent has just clam jammed Lily.

jam band

A style of band that may or may not understand the concept of a song but seems to care less. All songs are improvised nonsense. Imagine if you will, the theme song from the TV program Seinfeld being played for two hours in a continuous loop with drum and guitar solos as "accompaniment". As opposed to jazz fusion. Which is actually the same but with horns. The fans participate by playing hacky sack and smoking marijuana. This helps to distract their brains from realizing how terrible the music is. Sometimes there is singing but the bands have no real opinions on anything so it doesn't much matter.

Fans defend this with the oft uttered cliche: "They are all trained musicians and have degrees and stuff." The same defense taken to an extreme would be analogous to going to a dentist for a cleaning and coming out with dentures.

Possible reasons for the popularity of these bands would be that their fans do a lot of shitty drugs such as is the case in the "techno" scene.

I can't tell one of these jam bands apart from another. Are you sure this is a DIFFERENT jam band?

One is the Grateful Dead/Phish and the second is trying to sound exactly like the Grateful Dead/Phish.
