Humorous term devised by Kelly whilst musing over the different ways to incorporate the popular term "lol" (meaning laugh out loud) into new cutting edge terms. The term then became popular with many other people and can now be commonly heard in many of London's student circles. Recent reports suggest the term is also breaking into mainstream use.
Jon: "Yes you can use my microphone. . . "

Adam: (Into microphone) HELP!!!! I'm trapped in here with my friend!"

Kelly: "LOLACAUST!!!!"


Simone: "What other words are there as well as LOL???"
