/help $replace

$replace($1-,lol,Laughing Out Loud)

Also, you aren't specifying what you want to happen with that. You should have it look like this:

Code:
on *:input:*: {
  if ($left($1,1) == / || $ctrlenter) { return }
  if (lol isin $strip($1-)) {
    msg $target $replace($1-,lol,Laughing Out Loud)
    halt
  }
}
