I picked up the Truffle abrev however not the Tearfull one. Furthermore when you type in Trffl into google it asks if did you mean truffle. Therefore it could almost pass as a typo and IMHO it could be brandable.... not really qualified to provide a price tho. Or as weblord suggested developed yourself ;perhaps a truffle niche site (with ppc ads to stockists <up to $1.0 a click>)
