Idiom and slang and catchphrases exist for a reason. They convey a range of meanings and personality. Someone may be nervous or they may be concentrating on many things at once and not metering every word in real time. Or it may be entirely deliberate. Unless it obscures meaning or is disingenuous (unless it is delicious and deliberate irony), what of it? Maybe smoke more weed and it will relax some of ya'll a bit more. Falls off a high horse can be a *****.
