Rickyisms are modern day malapropisms, named for Mrs Malaprop from the 1775 play The Rivals by Sheridan, rather than malaphors.
The difference being a malaphor is a mixed up idiom like the examples in the post and a malapropism is substituting a word in a common saying or idiom for a similar sounding one. For example, "finding an escape goat" or "I resemble that remark".
