"fluffed" has a few different meanings, but in a rather narrow context. I suspect it is used more frequently in BrE.:
-A mistake, especially in the recitation of lines in a drama/play
"he fluffed the last line of the act."
- make a mess of, destroy or ruin;
-failed to perform or accomplish (something) successfully or well(used esp. in a sporting or acting context)
