I think this is what you want:

Code:
on $*:ACTION:/^(giggles at|grins at|laughs at|roars with laughter at) (.+) in (.+)$/:#somechannel:{
  if ($nick != cdc) { return }
  var %release = $regml(2), %section = $regml(3)

  ; do stuff here
}


Just modify the list of phrases to include all of the ones that you need to look for.
