You might want to change that on action a little
Code:
on *:ACTION:$($+(*,$me,*)):*:{
  if !%action. [ $+ [ $site ] ] {
    ; Check if $target is a channel or <You>
    if $target ischan { describe $target $replace($1-,$me,$nick) }
    else { describe $nick $replace($1-,$me,$nick) }
  }
  ; Prevent slapping frenzies if user had some similar script.
  inc -u30 %action. $+ $site
}
Add your popups by putting them into a new script file (Alt+A > File menu > New)
Code:
menu nicklist,query {
 .Slaps2
 ..one:echo -a your slap #1 goes here
 ..two:echo -a your slap #2 goes here
 ..three:echo -a your slap #3 goes here
}
