A cheat sheet! You rule.
I hope compiling it was more fun than the previous posts. I like the abbrev. DP. Hehehehe.
I’m glad you like it. There’s way more terms… but these are the ones that I will usually use on here.
Wow this list kicks ass. Can I rape and pillage it from you?
Why, yes… yes you can
This is extremely helpful, but what’s an “SO”?
I’ve been researching your entire blog, and found this, so I’m commenting. Anyway, the reason I’m doing so is because I really want to know what is what. You are SO YOUNG! OMGosh! I can’t believe this…so, with that, I’m going to look further into this disturbing matter, as it is so sad for me. Truly, Erin, I…just don’t know what to say.

This is great! Thanks! I was still guessing what various acronyms meant that I’ve been seeing around the net.
