Not only do words have multiple meanings, the intention of how they are used is also important. I didn't use the word as a noun or an insult, I used it as an adjective to describe the sound to a fellow english speaker. The fact that you are so offended about it speaks volumes about you because your attitude suggests you don't want to be associated with those with lisps, presumably because you see it as shameful.
