The name itself is probably worth the reg fee at the upper limit...think about it firend! This is a completely non-related term unless you are trying to suck on to a pre existing t-shirt selling entity in which case GIANTWEED thinks that such copycat actions are very lame to say the least...the original idea is what make the girl purr!
But if you want to develop you concept and market it beyond the twilight of your name then by all means feel free to do so!
Our team doesn't see it as more than a shadow box.
Once you get your spreadshirt or cafepress website up on it, re-post...and I would say based on revenue figures, you might actually get a descent appraisal. Good lucK!
