Bellows said about 420 plates are currently vulgar enough to be banned. Examples include thinly veiled profanities like “PHUK U2,” “IEATA55,” “L8RBTCH,” and “PPL SUC.” Online acronyms like “OMWTFYB,” which means “On My Way To **** Your Bitch,” and “OMGSTFU,” or “Oh My God Shut The **** Up,” were also included on Bellows’s target list.
