The rules are simple. Quote the post above you and change one letter in the 4 letter word (the quoting is to prevent posting confusion). You can not reuse old words in a particular round of changing. Try to get the person below you into a word that can't be changed without using. If the word is one that can't be changed, that person then says another 4 letter word. If the word they gave up on is later proven to have another word after it, resume from that point and disregard the round started after it.
Oh, with censored words, use the actual word, not the censor. If it does censor, say (censored) by it so we know that it is.
I'll start it off.
Love.
