TRUTHTMND is a fad centered around the hidden truth about what really is going on in this world.
These YTMNDs are usually stupid.
As Brother Ali put it, "Truth is here the truth the here, I said the truth is here, the truth is here!"
Now, someone competent needs to make this into a proper entry.
This fad was started by NiteSky on 1/21/2007, but in 2009 Uncircumcised, who invented this name independently, made a lot of TRUTHTMNDs, leading many to erroneously believe that he created the fad and not NiteSky.
