Ubertoast is essentially toast that is "better". It is like regular toast, but has been made into ubertoast thanks to a special toasting process known only by seven elderly Mongolian warriors living in Senegal.
Due to its uber-ness, only a few people are capable of eating ubertoast; among these are Chuck Norris, Mr. T and Christopher Walken. The toast is also so uber that, when saying the word out loud, you must shout it, as in "UBERTOAST!!!"
NOOB: Gee, I really love toast! Hey, what's this "ubertoast"?
CHUCK NORRIS: It's not "ubertoast", it's "UBERTOAST!!!" And you're not powerful enough to eat the UBERTOAST!!!
The best thing that could ever happen
something unreal or an out of body experience
a word used when expressing great emotion
beyond wording, the highest level of grandness
Mac - "hey allie how was your weekend"
Allie - "It was Ubertastic "
Mac - "sounds pretty amazing"
Allie - "you have no idea ;)"
