I'm not very good with abbreviations, but I know some. I need help 'translating' a few.

asdf
tldr

Thanks to anyone who can help me. I got a PM with a short message and these were in it, and I jsut want to know what they mean so I understand the whole message.

asdf is just the first four letters of the keyboard, sometimes used to express frustration. Tldr means: too long; didn't read, which basically states whatever you had to say was more than you had to, and no one cares what you just said.
