For malapropism Thesaurus gives:

abusage, barbarism, catachresis, corruption, cruel treatment, desecration, dissipation, exploitation, harm, ill-treatment, injury, malapropism, maltreatment, misapplication, misemployment, mistreatment, misusage, perversion, profanation, prostitution, rough handling, solecism, squandering, waste

I rather like

cat·a·chre·sis (kt-krss)
n. pl. cat·a·chre·ses (-sz)
1. The misapplication of a word or phrase, as the use of blatant to mean "flagrant."
2. The use of a strained figure of speech, such as a mixed metaphor.

...but it's a bit obscure and doesn't seem to have a verb. So maybe textecrate?
