(NEWSER) – Most kids can utter an expletive before they even know their ABCs—probably because their parents (and most other adults) have such terrible pottymouths, according to a new book. In Holy Sh*t: A Brief History of Swearing, Mellissa Mohr argues that English-speakers actually use a curse word about once every 140 words, theDaily Mail reports. That makes foul language as popular as first person plural pronouns like "our," "us," and "we." Among the book's findings:
- Cursing usually "kicks off" when a child is three or four.
- About 0.7% of all English words spoken on a given day are swear words.
