Obv

By now, it must be obvious that obv is short for "obviously." You're most likely to receive this abbreviation in chat and text messages, sent after you've said something that's plainly true. It's equivalent to (and conveniently the same length as) "duh."

More commonly, you'll see obviously shortened to obvi or obs. These abbreviations convey just a bit more character than the very straightforward obv. If someone uses obv, they're likely a straight shooter, who wants to make you feel a little silly for stating something so very obvious.
