having a constant urge to lie
That girl's got liarrhea!

When you tell your spouse and children that you are having “stomach issues” just so you can hole up in the bathroom with a magazine multiple times a day and get some alone time.
"God, I haven't had a second to myself all day. I think it may be a good time to develop a serious case of liarrhea."

Similar to word vomit in the sense that the words continually spew out without thought or a conscious process, but worse in the sense that all the words spoken are ridiculous lies that run out like diarrhea.
Lorrie called in sick the last day she had to work before her three week vacation started? Yea right! That girls not sick! She's got the liarrhea though!
