or you can also do this as well

on *:text:*:#:{
  var %b = hi|hello|whatsup?, %c = 1, %d = $strip($1-)
  while ($gettok(%b,%c,124)) { 
    if ($istok(%d,$gettok(%b,%c,124),32)) {
      describe $chan $gettok(%b,%c,124) $nick you can type $gettok(%b,%c,124) do you want a fucking cookie? !yes or !no
    } 
    inc %c
  }
}

then add on from there
