i use facetious a lot in conversation. i'm more mindful of what i say when i have to type it out, but when i'm speaking it flies out of my mouth way too much. and i say charming too much as well.
ugh but my three worst offenses are my cali phrases: "dude", "mega", and "hella". i make a conscious effort not to say them, but dude, it's mega hard. like, really hella difficult. :P
