It was my own fault. There were SEVERAL signs that I missed.

User: xiaoliusyeah, -6 rep...derp de derp  

(A. I forgot to double check his BTC address, it didn't have the funds in it.
(B. He took FOREVER (I found it strange, but didn't cotton on)
(C. He offered me a lower price than what I offered
(D. He changed the amount he would sell me at the last second
(E. He wanted me to put a message saying "yeeyay"

So obviously B, C, D & E add up to the conclusion he was buying BTC/something from somebody else, in scamming me to pay his guy.
