Eat my poop.

I came up with this tag line, "Eat my poop" when I made my Xanga account in April 2009. 

Eat my poop! Eat my poop? Eat my poop.

So, how did I come about with that phrase? Heard of "eat $h!t" which pretty much sums up "f*ck off"? Well, how about eat my $h!t, but substitute $h!t with my poop?
