dont include the trout part.. just do

on *:action:$($+(*,slaps,*,$me,*)):#:{ 
msg $chan thats how it is eh?
  .timer 1 2 describe $chan chases $nick with a gun!
  .timer 1 3 describe $chan fires!
  .timer 1 4 msg $chan $iif($r(1,2) == 1, damn i missed..., I hit! WOO!)
}

that way if they do something like /me slaps ... then it will still work
