Used at the end of texts or tweets that are so idiotic, so moronic that they had no reason to tweet or text it in the first place. These incoherent rants have such a strong sense of no thought, no logic, no reasoning of any kind behind it whatsoever, that it fails epically. In turn the crazed individual who texted the statement uses THX THO to come off sensible and break even with fail, only to fail again. THX THO can be used when breaking up with someone, Sarcasm, or Blaming God.
