Simul-core 

Meaningless, except for those "in the know". It means, literally, that someone on this planet or somewhere in the universe, is also listening to the same exact song you're listening to right now, beginning and ending at the same time, simultaneously, whenever you listen to music. A mockery of all the ___-core buzzwords used to hype this or that new band. In short, no one is as special as they'd like to think they are.

OMFG, I love Dick Wang and the Johnsons, they are the sickest simul-core band there is!

Soft Core Terrorist 

1. An individual who is always up to generally harmless but potentially disturbing or disruptive actions and antics. Example: One who discreetly releases known and or anticipated to be nasty farts in crowded store isles, elevators, cars or waiting rooms.

2. A soft core terrorist can be one who gets his co-workers all sensationalized with bogus, incomplete or sketchy information.

3> One who mindlessly creates undesirable conditions for others. I.e. blocking intersections, leaving a shopping cart in the way of four different people, leaving something nasty in a public laundry machine etc.

Person A: Jerome was all excited and had us all freaked out that something bad was happening.

Person B: He's a f--kin' soft core terrorist.

Alan-Core 

The type of clothes some "alan" would wear. This includes: Flannels, Beanies, Hoodies under flannel, corduroy pants, and vans (red high-top converses too). This style transcends ages and sexes and simply is a status quo for folks who wish to become "alan-esque".

You: Since when did you start wearing flannels and a beanie to work?
Me: Oh this? Ever since I started getting into Alan-Core!
