This word doesn't actually exist in standard dictionaries. That's because it's based on the verb 'impact' being used wrongly. 'To impact' doesn't mean 'to affect' or 'to influence'. If it did, then 'impactful' would mean affecting, effective, or influential. 'To impact' actually means 'to strike forcefully' or 'to press together'.
Usage: His misuse of the word 'impact' was really impactful.
