Shit thread, lock and ban. It's short hand for letting someone know that the post they put on the Internet is particularly worthless, and following the thread being locked their account should be banned.
A hazardous, geologic event wherein a hyper-accelerating flow of highly concentrated, sulfur infused volcanic magma builds, cools and intermittently cracks, avulsing into jaggedly uniform, mobilzed 'slabs' of densely toxic rock formations. In rare and unique environmental conditions, migratory slabs have been observed to spontaneously combust into abounding flames upon impact with proximate flora, fauna and curious homosapien onlookers, resulting in a enveloping expulsion of sulfuric cinder chards and respiratory impairing, noxious fumes.
1. "Did you see how the lava formed into 'Pyro-noxious Slabs' when it came down the side of of the volcano, cooling in rhythmic waves as it hit the oceanwater's edge?"
2. "I still can't believe that Drew was instantaneously incinerated into a sulfuric plume of ash when that 'Pyro-noxious Slab' chased after him while he was trying to take pictures!"
A slabdab is the inhalation of the vapors produced when someone vaporizes a slab (large amount of concentrated marijuana THC in the form of wax, hash, or etc., pressed into a flat sheet).
This is usually done by placing the slab onto an extremely hot piece of metal that has been heated by a blow torch.
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
Short-hand for the word floccinaucinihilipilification, meaning the estimation of something as valueless (encountered mainly as an example of one of the longest words in the English language).
