So in light of the feedback I got (thank you kindly) I did more font-hunting and I think I've found a great one.
This one I think carries all (or at least most) of the weight I was looking for, and has the added qualities of not requiring large blobs of black or a bunch of 'spatter' looking bits or jagged fine details to get the 'battered' point across. This font is very simple but ragged, in a way that I think will translate very well to a tattoo.
I have it printed out at the size I'd wear it, and it doesn't lose any detail at that size and I've seen text tattoos that use much finer fonts. All in all I think this is the one. Feel free to let me know if you think otherwise. :)
I'm planning on visiting the tattoo folks tomorrow to see what they think. :D
No, no poop this time, but I do have pictures of the poop to Batman scale on the whiteboard, lest you think me untruthful. :D
