Now this is a word that really irritates me. I'm not intentionally trying to pick on you Joe (this time), for your recent use of this ridiculous word because so many people use it. I was really surprised to see the Yahoo dictionary take such a damning stance on the use of this word (click here), though I wholly agree. I will sum it up: People use it when they are trying to sound proper, despite "the logical absurdity of combining the negative ir- prefix and -less suffix in a single term". I'm sure my concern means nothing to the phonically challenged Simethicorn, who derives his his own sense of identity, from his aptitude for muddling the medium through which we communicate.
