This one's for Mark

In an attempt to help reldnahkram's efforts to bring more fun to LJ, here's a communal quiz:

There are slang words which are nouns, adjectives, etc... *how many* parts of speech have examples of (non-obscure) slang? Are there slang prepositions? Conjunctions?
1 point to the group for each different part of speech.

I'll toss out the first one. Adverb: Hella.
