1. Vitally important; essential.

2. Misused to express awe, difficulty, or pain, probably arising from some moron that meant "excruciating", but was too much of a semiliterate fucktard to understand the difference.

Semiliterate: An adjective describing the state of being only partially or poorly literate. A semiliterate individual may struggle with reading, but their partial literacy is particularly evident in their writing.

Using slang is not itself a sign of being semiliterate, but knowing only the slang definitions of many words may be.

Consistently using the wrong spelling of similar-sounding words such as "their", "there", and "they're" is another common sign of poor literacy skills.

Perhaps the most frustrating sign of semiliteracy is the use of 'netspeak' or 'txt-speak', wherein the writer abbreviates short and simple words for no reason beyond laziness.
