(lisp) 이거한국어로 뭐라고해요 ? A lisp is a particular pronunciation problem that some people have in English. It means that when they say a word with an "s" sound, they say it wrong, and use a "th" sound. For example, if I was trying to say the words "See the silly seagulls" but I had a lisp, it would sound like "Thee the thilly theagulls".
