An incredibly informal use of the terms such as : "incredibly good"/"well-liked"/"good".
Usually the
word would be used in situations where two or more people communicate to each other how they view their opinions on (a) certain intaty('s), usually noun/opinion/adjective, and even more usually used on forms of food.
The
word originates in slang culture in North America, most likely having its roots in the
word "busting", implying that the
word originates from after one would masturbate/ejactulate, after the sexual climax one would just had been finished "busting"; henceforth evolving in
slag culture being used so commonly as a form of (in simplest terms) "good". Therefore, the
word itself would grow into a New-England North American accent, evolving into the
word "bussin"
(The
word could also be used in a double conjoined sentence, where one's object/view would be *so* well liked, one would use the term "Bussin' Bussin'" to emphasize major forms of pleasure)
