The "photo crasher squirrel" first made its appearance in a holiday photo. He is a key example of photobombing.

Authorities on the English language — the folks behind the Oxford Dictionaries Online, to be specific — have once again acknowledged the significance of words we'd invented during late night online chat sessions. Yes, this means that "lolz" and "mwahahaha" are now in the dictionary.

Before you reach for the pitchforks or torches and threaten to burn down every English classroom in sight, let's clear something up: You shouldn't confuse the Oxford Dictionaries Online (ODO) with the Oxford English Dictionary (OED). One focuses on the current state of the English language and "includes modern meanings and uses of words," while the other is more of a historical record, tracking core definitions. 

"Research from the Oxford Dictionaries team shows that these terms have made their way into common usage," a blog post announcing the latest additions to the ODO explains. "The world of technology remains a major influence on the English language, with innovative advances reflected in new entries."

You can check out the full list of words recently added to the ODO over at the OxfordWords blog, but here are some which stood out to us:

ethical hacker - a person who hacks into a computer network in order to test or evaluate its security, rather than with malicious or criminal intent

hackathon - an event, typically lasting several days, in which a large number of people meet to engage in collaborative computer programming

hat tip - (in online contexts) used as an acknowledgement that someone has brought a piece of information to the writer’s attention, or provided the inspiration for a piece of writing

inbox - (verb) send a private message or an email to (someone, typically another member of a social networking site or Internet message board

lifecasting - the practice of broadcasting a continuous live flow of video material on the Internet which documents one’s day-to-day activities

lolz - fun, laughter, or amusement

mwahahaha - (also muahahaha, muwahahaha, buahahaha) used to represent laughter, especially manic or cackling laughter such as that uttered by a villainous character in a cartoon or comic strip

photobomb - spoil a photograph of (a person or thing) by suddenly appearing in the camera’s field of view as the picture is taken, typically as a prank or practical joke

tweeps - a person’s followers on the social networking site Twitter

UX - short for user experience

video chat - a face-to-face conversation held over the Internet by means of webcams and dedicated software
