A malapropism occurs when two people use the same word to mean two different things

It is false that a malapropism occurs when two people use the same word to mean two different things.

A malapropism is the use of an incorrect word in place of a word with a similar sound, resulting in a nonsensical, sometimes humorous utterance.

An example of malapropism is, "Texas has a lot of electrical votes", rather than "electoral votes"
